The interview process is claimed to be "unbiased" - you are interviewed by multiple people that are not connected to each other, and each has to give you "+" or "-", for you to move forward. I had 7 interviews and 3 assessments, spending about 40h on the overall process, after which i was politely rejected without given any feedback. I understand they want to be cool and advanced, but this is just a poor attitude to candidates - asking to spend so much time and giving 0 feedback. I have asked for a feedback a few times, but no response.
My feeling was that it's highly biased, because one person can block the whole process. At some point i knew i wouldn't be taking a job there, just by talking to employees, interviewers, asking them questions, and getting hints about the culture - super demanding (which is ok), but also no processes in the company (according to few interviewers). Many key decisions require executive approval, which contributed to the impression of a highly centralized decision-making process. It might be a good partner for other companies, but it surely doesn't treat it's employees and candidates with respect. They also warned me that i'd have to buy my own computer as an employee, and by the way, they don't hire in all locations for a full-time employment, for most countries it's contractor, with 2 weeks notice period, and they spend 3 months hiring a person... This tells a lot about how company works.
After this process i have 0 belief that they are unbiased.
