I had three interviews. One with HR, one with lead and manager and another one with other managers. Very friendly and helpful people. Very welcoming. Questions were easy but require critical thinking. Combination of behavior questions and technical questions. Excellent interview process. Very fast and responsive.

I met HR during the university career fair. Was contacted by him right after it ended asking whether I was available to meet the team. I was asked (informally) some questions about my resume and then was told that I will receive further steps by email. In about a week I have received Hackerrank challenge to complete. There were 2 coding questions and 4 theoretical knowledge questions. Basic Data structures / Classes / Sorting questions, easy-medium level. The week after I finished the test I was contacted to schedule an on-site interview in my area. 4 rounds, 1 hour each. 3 with developers and 1 with a Project Lead. For each I was asked to go over my resume and then to solve 1-2 whiteboard questions. Difficulty was medium mostly for all of them, single one was a little bit harder than the others. Nothing surprising or completely off limits. Was contacted by the HR in about two weeks by phone with an offer. Great experience, no delays, everything goes as expected.
