I applied through an employee referral. The process took 4 weeks.

Nothing is very clear during the process. But well, after going through the whole process, after the last stage I received an email stating that they were not going to continue with the process. They didn't even give a good reason, they just mentioned that they considered some factors such as "team need, seniority levels and repertoire". Hilarious to say the least, if not frustrating. It was the same way years ago when I tried an internship there. Honestly, I'll never go near them again. After this one, I'm even stopping being a client. EDIT: they sent me an email with more details, a list of positive and negative points. SEVERAL very positive points and, believe it or not, all the negatives were very silly details that tend to occur in any interview due to the candidate's nervousness, such as:

• Not giving very informative names to architecture services, no matter how wonderful the solution is. Yes, names lol.
• Unit tests for smaller functions. I always write code TDD style, however, when you are in an interview, the last thing you think about is writing tests for each and every function. Especially when you are using a compiled language and the data structure changes.
• Having spoken in a very macro way about how I contributed in previous companies. Yes, I was the interviewee, but who had to know if the interviewer wanted more information was me lol.

Anyway, these were the negative points listed by them. It seems that they don't want to hire people. They want robots.

In the final phase, there were questions regarding the reasons why I decided to leave previous companies, about diversity, culture, etc.
