It was pretty standard, asked me to go over my portfolio and then gave a rough idea about the projects and tasks that I would be working on that summer.
I got interviewed by the Houston office several years ago. It's a general process: Introduction, portfolio review, some general questions and the interviewers' introduction of the firm. Went very nice and it was about 40 min.
Applied in company's website. Then, in 3 weeks, a hiring manager contacted me. Set up an interview schedule and meet with two architects, principal and senior associate, in zoom. Overall interview process was normal.
