Since the person who works at HR was on vacation(they mentioned in email), I started the interview process by first talking to the engineering manager. It was very positive and they emailed about he really enjoyed our meeting, I passed that technical part. A few days later HR set a meeting. The HR woman asked a few very simple questions like where would you like to live if you relocate here, kind of questions that doesnt even require taking notes, which she didn't. That meeting passed about 5 minutes in a positive way as well. After a few minutes end of the meeting, I recived another email from her about asking my age which I am 27 years old. A few days later they replied with negative email about the process. I think they found me "old" for a mid-level software engineering position.

It was super fast and reliable. You do not spend all week finishing the case. Interviewers have good communication skills and they help you when you struggle. The interviews process had 3 steps after 30 minutes HR meeting, you receive a case. The first step we went through the case and talk about the details. The second step was the technical interview and the last step was a cultural fit. Each of them took one hour. It was clean and super fast.
