Oura Sr. Software Engineer interview questions

The interview started with a referral from an old colleague. The interviews were scheduled quickly. There were 4 rounds with the whole process taking 20 days from initial contact to offer. The 2 technical interviews were a whiteboarding session and a online coding challenge. The coding challenge was about implementing algorithms using my own chosen tools. I used Python and VSCode.

The recruiter was great as she seemed really excited about my 20 years experience. Then it all changed with the hiring Manager interview. First off, he was late and only left me 4 minutes to ask questions at the end. He didn't even know what job i was interviewing for until the end when I was able to ask a question. He had to ask me!! I realize that my interview was at the end of the day and he was bored, but he could have shown some enthusiasm. No personality - I felt like I was talking to a wall. Zero interaction with him. Zero questions regarding my experiences. He just asked 'check box' questions from a list. Really sad experience.
