Hi everyone! I recently appeared for the Infosys HackWithInfy (HWI) interview, and I thought of sharing my experience here because it might help other students who are preparing for the interview.

This was one of my first experiences with a company like Infosys, so naturally I was a little nervous before entering the interview. I had prepared mainly around my programming fundamentals, DSA, CS subjects, and the projects and technologies mentioned on my resume.

The Interview

The interview started with a simple introduction. The interviewer asked me to introduce myself and then gradually moved towards my academic background, technical skills and projects.

The interview was not just about answering direct questions. In several places, the interviewer asked follow-up questions based on what I answered. So I felt that having a clear understanding of the concepts mentioned on the resume was much more important than simply memorising definitions.

Technical Discussion

The technical part covered my programming fundamentals and computer science basics. Questions were asked around concepts that I had mentioned in my resume and areas that are generally important for a software engineering role.

There was also discussion around DSA/problem solving, where the focus was more on how I approached the problem and explained my logic rather than simply giving an answer.

The project discussion was another important part. I was asked about my project, the technologies I used, my contribution, and how different parts of the project worked.

One thing I realised during the interview was that when you mention a technology or project on your resume, you should be prepared for the interviewer to ask you questions from it. Even a seemingly simple project can lead to several follow-up questions.

HR / General Questions

Towards the end, the discussion became more conversational. Questions related to my background, career interests and my expectations as a fresher were discussed.

The interviewer also gave me an opportunity to ask questions, which made the overall interaction feel less like a rapid-fire interview and more like a conversation.

My Takeaway

Overall, the interview was a really good learning experience for me.

The biggest thing I took away from it is that strong fundamentals + knowing your resume + being able to explain your thought process matter a lot.

If you're preparing for HWI or a similar fresher interview, I would suggest:

• Don't put anything on your resume that you cannot explain.
• Revise the fundamentals of your strongest programming language.
• Practice basic to medium DSA problems and focus on explaining your approach.
• Revise OOPs, DBMS/SQL and other core CS subjects.
• Be ready to explain your projects from both the technical and practical side.
• Don't panic if you don't know an answer. Take a moment, think about it and communicate your approach honestly.

I'm still waiting for the final outcome, but irrespective of the result, appearing for the HWI interview itself was a valuable experience for me.

Hopefully this helps someone who is preparing for their Infosys interview. All the best to everyone preparing! 🚀

I'm using a free tier, and since there is access to one free planly feature, I registered in that, and in day-1 lectures, the internet and backbone video from CN is not working and asking for subscription. Pls fix this bug.

By the way, the planly feature is awesome!

I was selected after Amazon HackOn, followed by their online assessment, which tested algorithms and development skills. Their interview mainly focused on Algorithms and leadership principles.

The focus was on writing optimal code and explaining why you used a certain data structure, followed by TC analysis. It will feel like a technical discussion: explain each question; ideally, you'll be asked 2 questions. Apart from these, read up on Leadership Principles.

The questions I was asked revolved around bit manipulation, LRU cache, and Binary search Trees.

Hope this helps. Good luck!

Many previous links are not work, I was using System Design Road Map now link show 404 you not found

Basic blogs that were attached to each topic are nowhere to be found and leetcode links are kind of hidden i request the team to fix this please

Hey Team

I am a data engg with an overall experience of 4 years, I wanted to bring to your notice that for a data engg we need to be jack of all trades and master of one to be up for interview. SQL, Spark, Databricks/Snowflake, Data modelling, Data governance, Kafka, Lakehouse, Data ingestion etc should be in our list. So the ask is big but this can be a deal breaker for everyone

Preparing for placements or technical interviews means balancing learning, practice, revision, doubts, and company expectations.

ZENKAI brings these together in the updated takeUforward experience. From personalised planning with Planly to free coding practice, TUFY assistance, company preparation, and spaces for your notes and code, each feature supports a different part of your preparation.

Beginners can follow a path that builds concepts progressively. Experienced learners can choose sheets that address specific gaps. Free and TUF+ learning options sit within the same structure, with access depending on the resource and your plan.

Free Practice: Run code, submit solutions, and improve

TUF Practice is open to everyone, with unlimited code runs and submissions.

The DSA practice platform lets you explore questions by topic and pattern, test approaches, examine failed cases, and submit improved solutions.

The platform also includes SQL practice for joins, aggregation, subqueries, window functions, and other query-writing concepts.

Placement preparation extends into quantitative aptitude, logical reasoning, and verbal ability, with learning resources, practice sets, and mock tests.

Premium company collections, learning material, aptitude resources, and AI assistance follow their respective access rules.

Problem of the Day: Build a daily coding habit

The Problem of the Day, or POTD, gives you a regular coding challenge to attempt. Work through the problem, test your approach, and review what you learned.

The calendar archive lets you revisit earlier challenges, retry a question that needed hints, or return to a pattern you have not practised recently. Eligible activities also offer coin rewards under the current rules.

Add difficult questions to a revision list so you can attempt them independently later.

TUFY: AI assistance while you learn and practise

TUFY is your AI learning companion within takeUforward. Use it while studying concepts, writing code, or following your preparation roadmap.

Its learning support includes:

• Contextual doubt assistance: Discuss the lesson or problem you are working on.

• Progressive hints: Get guidance towards the next step.

• Code review: Examine logic, complexity, code quality, and edge cases.

• Personalised solution notes: Capture learning from your submission.

• Interview follow-up questions: Practise explaining or adapting your approach.

• Frequently occurring doubts: Revisit common points of confusion.

TUFY uses credits, with allowances depending on your plan or pass. Check the TUF+ pricing page for current allocations.

Company Preparation: Focus on your target interviews

Company collections within DSA practice organise questions associated with different employers. Company tags and available frequency or recency information help you choose what to practise.

Use them to identify patterns, revisit weak topics, and build a preparation list around your target company. Combine question practice with interview experiences to understand where coding, SQL, Core Subjects, or design may need more attention.

Company questions guide preparation; they do not guarantee what an interviewer will ask. Practise explaining your reasoning and adapting solutions to different constraints.

Community: Learn from interview experiences

The takeUforward Community brings together interview experiences, success stories, and preparation discussions.

Read about candidates’ rounds, questions, follow-up discussions, and outcomes. These accounts can help you understand the role of DSA, machine coding, projects, and technical fundamentals in different interviews.

You can also share your own experience and contribute details that help others prepare for similar opportunities.

Dashboard: Begin your daily preparation

The takeUforward Dashboard connects you with Planly, learning progress, popular preparation paths, interview experiences, POTD, and your daily planner.

Open it when you return to study, review your tasks and progress, and choose your next activity. Sign in to access the personal progress and planner information associated with your account.

All Lists: Organise problems for practice and revision

All Lists, previously called Bookmark Lists, is the home for your custom problem collections.

Create lists for questions you solved with hints, topics you want to revisit, or an upcoming company interview. Keeping those problems together gives each practice session a clear purpose.

NoteSpace: Keep your learning ready for revision

NoteSpace gives your study notes a dedicated place. Create notes with AI assistance, refine them in your own words, and organise them for revision. Download options let you keep supported material for later use.

Capture the reasoning behind an approach, the conditions it depends on, and the mistakes you want to avoid repeating. These details make your notes useful when you revisit a topic.

CodeSpace: Save the code you want to revisit

CodeSpace is your personal space for saved code. Keep useful solutions together, organise files into folders, and return to earlier approaches during revision.

Create folders around topics such as graph algorithms, binary search, or linked lists so relevant implementations are easy to find.

When we purchased the Pinnacle Lifetime Plan, our understanding was that it would provide us with comprehensive interview-related content in one place, covering all the major areas required for interview preparation, including DSA, Core, LLD, and HLD.

Based on that expectation, we were happy to see LLD being added to the Pinnacle Plan, as it aligned with what we understood the lifetime plan to offer. However, we are now disappointed to see that HLD is not being included in the Pinnacle Plan (Plus Core) and has instead been moved to the Plus Max plan.

This is concerning for existing Pinnacle users because the value proposition we considered while purchasing the lifetime plan was having access to the complete interview-preparation ecosystem without having to purchase additional plans later for individual components.

When a user invests in a lifetime plan based on the understanding that the platform will continue to provide comprehensive interview-related content, moving an important area like HLD into a separate paid plan can feel like the scope of the original commitment is being changed after the purchase.

We completely understand that new courses, features, and premium offerings may be introduced over time, and we appreciate the effort your team puts into continuously improving the platform. However, we believe that core interview-preparation content such as DSA, Core, LLD, and HLD should ideally remain accessible to existing Pinnacle Lifetime (Plus Core) members, especially when the plan was purchased with the expectation of having all interview-related preparation in one place.

Otherwise, existing users may feel that they are being asked to pay repeatedly for content that they reasonably expected to be covered under their lifetime membership.

Pinnacle Lifetime (Plus Core) members are currently told that certain areas will be provided in the future, what assurance do we have that those commitments will remain unchanged? If the scope can be altered later, then users effectively have no predictable understanding of what their "Lifetime" membership will actually cover over the long term.

We are not against the introduction of new premium offerings. We understand that the platform needs to create new products and revenue streams. Our concern is specifically about essential interview-preparation content that reasonably falls within the scope and purpose of the Pinnacle Lifetime Plan (Plus Core).

We request you to please reconsider this decision and look into providing HLD and other essential interview-preparation content to existing Pinnacle (Plus Core) Lifetime members as part of the plan. We therefore request the team to reconsider the decision regarding HLD and make it available to existing Pinnacle Lifetime (Plus Core) members.

Note: - We would appreciate some clarity on what content is guaranteed under the Pinnacle Lifetime Plan (Plus Core) and how existing customers will be protected from such changes in the future.

I applied to Autodesk for an SDE-1 role through an off-campus opportunity, and my process had multiple onsite rounds.

Round-by-Round Experience

Round 1: Manager and Resume Discussion

My first round started directly from my resume rather than DSA.

I picked one of my projects and explained the problem I was solving, the overall design, how different components interacted and what I had personally implemented.

Whenever I mentioned a technology or design choice, I had to explain why I had chosen it.

I was also asked questions from Computer Networks, Operating Systems and basic security concepts.

Round 2: Arrays and Target Sum

Here, I received a problem involving two arrays and a target sum. I had to find the minimum combination satisfying the given target.

Before coding, I explained my initial approach and then worked through possible optimizations.

I also had to dry-run my final solution and discuss how it would behave for different inputs.
Similar problem:

Round 3: DSA

I received two different problems in this round.

My first problem involved a circular linked list, where I had to determine its head. I had to reason carefully about the pointer relationships because there was no normal NULL ending like a regular linked list.
Similar problem:

My second problem was to search for a target in a matrix.

For both problems, I had to explain my reasoning rather than jump directly to the final code.

Round 4: Internship and Technical Discussion

A major part of this round was based on my six-month internship.

I explained what I had worked on, the responsibilities I owned and some of the technical decisions I had made.

My answers naturally led to follow-up questions around my projects and core CS fundamentals, so I had to connect what I had learned with what I had actually built.

Round 5: Final Manager Discussion

My final discussion again went back to my resume.

I was asked about implementation details, technical decisions and why I had chosen particular approaches in my projects.

I also answered a few fundamental questions and explained how those concepts connected with my actual work.

For me, this felt less like another new technical round and more like a final check of how deeply I understood everything I had presented throughout the process.

Interview Result

I completed all the interview rounds, but I hadn't received the final result when I shared this experience.

The biggest thing I noticed during my Autodesk process was how frequently my resume and projects came back into the discussion.

Cant submit the codes even i am having paid subscription

...is anyone facing the same issues??

for some questions when i am trying to view the solutions its showing me this and not displaying the entire editorial which contains the code.

What's covered in video + editorial

How does the Brute Force approach solve the Next Smaller Element problem?

• Understand how direct checks find the Next Smaller Element for each array value
• See why this approach can become slow for large arrays
• Learn how the result array stores NSE values, including cases with no smaller element

View the Brute Force explanation, code, and analysis

it just shows what's covered in the video but not able to find any vide attached . Anyone else facing this issue?

I am not able to access any writen material for core cs subject.

Sir so im using free plan , where I created the plan but while learning in sprint/daily tasks , im also getting java videos, which I don't even selected and also there was not an option for selecting the language still getting that videos.

I subscribed to the Pinnacle 12-month plan about a month ago. However, I am currently unable to access the DSA videos included in my plan. I have checked my account, but I am unable to find the DSA videos or locate where they are available.

Could you please check my subscription and help me access the DSA video content included in my plan?

Hi , Can anyone tell me why pinnacle plan is showing expired? It's supposed to be for lifetime as promised at the time of launch. Could you guys please fix this?

Guysss i am new here.. but the thing is i am not able to view the detailed section of this..i tried clicking on the title but still its not opening..i did click on the three dots too but t there is nothing there...does anyone know how to oepn this detailed view..if yes pls help me!!!!!!

🚨 Bring Back the TUF CP Sheet!

The Take U Forward CP Sheet has been removed, and many competitive programmers who were using it for structured practice are missing it.

TUF sheets have always been a great way to: • Follow a structured problem-solving path • Practice important CP concepts • Track progress consistently • Prepare for coding contests and interviews

For many of us, the sheet wasn't just a list of problems — it was a roadmap for improving competitive programming skills. 💻

🙏 Request to @takeUforward / Striver: Please consider bringing back the CP Sheet, or provide an updated version if it has been replaced.

It would be really helpful for the CP community!
