On campus interview held in college, interview went for 15 minutes. Everything went well, asked few hygiene questions. Confidence did good to me would advice to have the same during interview. Prepare HR answers well along with technical questions

1 Pre-screen, 1 phone interview, and 1 in-person (3 different meetings). Basically painless, except I was made to do a case study even though I was interviewing for a software engineering position. Not a difficult case study though, basically just work through it and explain your thought process to the interviewer.

Online test - where you have to answer some technical questions Technical round - where they will ask you about your prior and existing experience Managerial round - regarding your future goals and difficulties HR round - Salary and perks
