I applied online. The process took 3 months. I interviewed at Oura (Espoo) in Feb 2022
Interview
Process consisted of only interviews with several people. Interviews were friendly, pleasant and helpful. I enjoyed all of them and would have enjoyed the process even if I was not hired.

Question 1
I was asked about my previous work and then some more detailed questions about it.
Complete ghosting - there were more than month intervals between interview steps. There was not any clear description about reject. Interviews were super easy and not challenging at all. Will try to avoid next time.

Question 1
Classic questions about working experience and hard skills.
I applied through an employee referral. The process took 2 months. I interviewed at Oura (Helsinki, Southern Finland) in Nov 2024
Interview
HR call -> team lead interview -> job-related assignment (scheduled a time and had a specified time-window to report back) -> technical interview -> meeting with a higher leader. The process went smoothly, I was always informed of decisions and next steps within a couple of days.

Question 1
Why is overfitting a problem in data science and how do you take that into account?
The interview process consisted of four separate interviews (the HR interview, a technical interview with the team supervisor, a non-technical interview with the supervisor of a closely collaborating team, and finally the department head) and a timed programming task. The technical interview and task were reasonably challenging. The communication interval was approximately one week.
