I applied online. The process took 5 weeks. I interviewed at CERN in Jun 2021
Interview
The process is composed of asynchronous interview, board interview and technical interview. Asynchronous interview has a mixed set of technical and behavioral questions. Human resources are extremely helpful and supportive through out the process.

Interview
3 stage interview. I was well informed about every stage and next steps. Questions were relevant. Interviewees let me have a QA session which was very helpful. I had a positive experience.
Three-stage interview. First was asynchronous interview using Sonru. The second stage was the coding exercise and finally panel interview followed by a test and "meet the team activity" (all 3 activities in one day). To sum up, I invested like 8 hours total of my time in this process, and in return, I received 50 seconds voicemail message around 19 on Friday with feedback that they selected someone from inside CERN (there were 3 other people besides me in the final stage). The message included a promise that if I want to hear more feedback I should contact. I wanted to follow up to receive more info, called back 2 times, mailed once but I got no further response. This is my real issue with this process, I invested so much time to get 50 seconds in return. I would definitely score this experience neutral or even positive if I would get more in return.
