I applied via Naukri.com and was interviewed in May 2024. There was 1 interview round.

Round 1 - Technical 

(1 Question)

  • Q1. Tech panel did not show up

Interview Preparation Tips

Interview preparation tips for other job seekers - Very Bad Process. They kept rescheduling the interview call.
First they scheduled the Technical interview. Sent the invites & then when I joined at the particular time - HR came on the call instead of tech panel & told that interviewer is busy ,got some other interview going on. So, cant have it right now.
This kind of thing happened 3 times where none of tech panel show up.
Very bad. Not expecting from such a big company like Wipro.

Afterwards, they dont even pick call. They just call randomly & setup an interview. And then cancel it. Very unprofessional.
