I applied online. I interviewed at Tru (Punja) in Mar 2025
Interview
It was a 3 round process:
1. Telephonic round with HR asked few basic que around nodejs, reactjs, nextjs.
2. round 2 got scheduled on google meet with 2 tech leads: asked alot of question around nextjs, nodejs, event loop, mongodb, postgres.
3. Final round with Some Senior Manager again got alot of questions on optmisation in nextjs, reactjs, got a join query problem on 3 tables.
After 2 days got rejection email, I was not able to perform good in DB related questions so I already knew the outcome.
