At first sight, this company looked very serious. A recruiter called me to ask if I would like to work for them. I said, "Let's try!" A week later, they scheduled a remote interview session. I passed it, and one to two days later, they scheduled a series of three one-hour technical interviews where I met with five interviewers. They mainly asked questions about algorithms and data structures, and there were some questions about architectures. I think all conversations were a pleasure. I answered every question, and at the end of each round, we agreed that we had found a good solution on the whiteboard. I asked the interviewers which team they were looking for candidates for, but they said they were looking for candidates for multiple positions.

BUT after that...

I waited for feedback for more than 10 days. When I asked if they had any updates, they responded within a day: "The team has decided not to move forward with your application at this time. Please note that this decision should not be interpreted as a negative judgment of your personal capabilities but is purely arrived at as a result of matching the specifications of the job we are trying to fill."

So, I was not matching the specifications of the job. What job? They said they were looking for candidates for multiple positions. And why was I not matching? Not matching to what? Every interview went well, all questions were answered, and each interview concluded with an agreement that the outcome was good. The interviews themselves couldn't be the reason for refusing me. I have been a Senior/Lead developer/architect for many, many years at very serious companies, like EPAM and GE, so my experience is more than enough for them. The interviewers were sympathetic, and we talked in a good mood, so that's fine too. They didn't give me an offer, and we never talked about salary, so that shouldn't be a problem either. Thus, the late negative answer was a real surprise.

I do not recommend this company to anyone. This is a very unserious company, and the interviews are a waste of time. Please avoid this company!
