Advice from candidates

77 pieces of advice, in their own words. Names removed.

• Tip for Zomato: Make sure you are really well-versed in DBMS. As was the case with me, you may be asked to do a complete database design wherein they will extensively and thoroughly test your DBMS knowledge. I’d recommend practicing some database design problems beforehand.

  Round 3: Technical Interview · 2024-25

• One suggestion I will give is to ask curious and genuinely interesting questions to the interviewer at the end. Try not asking something very generic, or just for the sake of it.

  Round 3: Technical Interview · 2024-25

• General tip: Always try to appear happy, calm, and confident in all your interviews, and always end your interviews by asking an interesting question on which you can have a good discussion, it leaves a good lasting impression.

• For the OA, you need to have some practice in giving timed contests. I used to give contests on Codeforces and virtual contests on LeetCode.
