For the interview with HNTB, I had to face Two interviews. 1st one is very basic. They asked qs about both my resume and my expertise. They took individual projects from my resume and asked about what I did as a part of the project. The second one was very technical. The technical interview was difficult. In the technical interview, they came up with a questionnaire and I was asked to give answers to each question within a time window. The overall interview duration for 1st one is 30mins and for the 2nd one is 1hr.
