I applied through a recruiter. The process took 2+ months. I interviewed at Sonar (Geneva)
Interview
The interview process had 5 steps.
I will describe the 4th step, because the previous comments make it look scary, even though it is not.
It took place at their offices in Geneva and it was conducted by a lady working for an external agency handling People & Culture interviews. It took around 2 hrs.
I believe it is meant to build a profile for you and see if you are a good fit for the company culture. This is very useful for both the employer and the candidates because it is desirable to work in a company with compatible individuals and values.
You have to focus to answer very precisely to all the questions, as there are a lot of them.
It was a pleasant experience, the interviewer was very friendly and I didn't even realize how the time passed by.

Question 1
I was asked more questions related to describing various difficult situations at my work place and how I handled them (real examples, not hypothetical ones)

Interview
I am genuinely disappointed by my interview experience with Sonar. The staff I met were incredibly friendly, and I truly believe they have a strong product that would have been exciting to sell. Unfortunately, the interview process itself didn't live up to that positive first impression.
The company utilizes a lengthy five-to-six-round interview process. By the third round, candidates are required to build a project and deliver a 20-minute presentation. I was only given a few days to scramble and put this together, but it went fine.
What really disappointed me, however, was what happened next. After dedicating that time and effort, I was completely ghosted, receiving no rejection email or follow-up of any kind. When a company asks candidates to spend their personal time working on a project, it should come with a baseline level of human courtesy.

Question 1
How do you handle a customer emergency when you can't get ahold of leadership for an answer?

Interview Experience:
Interview process was straightforward and the conversation itself went well. The recruiter joined the scheduled call about 10 minutes late but was otherwise professional during the interview.
After the conversation, I was told I would be moving forward in the process. However, there was no communication for several weeks despite this update. I eventually received a follow-up stating that the role had been closed and that another candidate had already been far along in the process.
Overall feedback:
Clearer communication and more transparency around candidate status and timelines would greatly improve the experience. It was confusing to be told I was progressing, followed by a long period of silence and a delayed update and rejection. Raised some concerns for me as a candidate.

Interview
Four rounds of interviews, with a take home/presentation challenge. People and culture fit interview as well which was surprisingly robust. The culture fit is taken very seriously, and you should prepare accordingly.
