• Start building your personal brand on LinkedIn. Try to post one thing every week atleast on things that you're learning. Since Hiring Managers look there, it makes sense to polish it as much as possible. (Thanks Ribhu)

18th Feb, 2026: Now that I'm a Senior lol, here's what's worked for me: DSA and doing course projects myself has helped me the most I think (thank god GPT3 was not great at generating code back then).

Honestly placements is a lot of luck+hard work. Work as hard as you can. I would also recommend applying online to any openings. Krishan Kumar, Talentd. Get referrals from seniors or anyone you can.

Polish your resume with any project that you can speak about for more than 10 min. Anything that solves a personal pain point for you I think is really liked by the interviewers. Can spin it into a story which leaves a positive view.
