Message to Aspiring Students:

Do a lot of DSA, Learn CS Fundamentals. Solve company-wise problems from Leetcode/ GFG. Read a lot of interview experiences. Don’t over exaggerate things in your resume, you might face questions on them. For a few companies, do system design as well. Things will work out, stay positive ☺.
