Their interview process was fairly organized and pleasant. I liked the people I met as well. Unfortunately, the pay was WAY under the market for their data science positions, so I had to decline. They wanted me to manage people too, but couldn't even match my current pay. I was shocked! This was supposed to be a successful high paying hedge fund, but not for data science roles, apparently. I was very upset about this.

Interview
A lot of interviews, very thorough:
- Initial interview
- 2 technical interviews
- 2 soft skill interviews (project management, team management)
- Final interview
Tech interviews consisted of Python coding tasks (algorithmic and practical data analysis and model) the latter is simple enough to be finished within the interview framework but requires complete solution - from data to finished model analysis, so pretty involved.
The soft skills interviews are pretty standard in nature except usually combined in one while separate at Voleon.
Been told that I'm doing great all through the interview, then after all rounds they kept me waiting for the answer for quite a long time, and finally declined.
