There are 4 interviews: 1 behavioral and 3 technical. Each about 30-45 min long with different employees in the company ranging from new hires to seniors. I interviewed in early October 2020. The people are nice to talk to and seem to like learning things about you.

I was contacted by email to set up a phone screening after they found my resume on my university's website. The phone interview was around 20 min, I was asked numerous technical questions. I botched a few. I got an email later that day that said my time and interest were appreciated but they couldn't take me because they had a great pool of candidates.
