There was an initial 1-hour phone screening with their functional programming HR. He seemed like a nice guy. This was the only time I got to interact with him, as he then went on paternity leave.

I explained I was in a bit of a hurry, as I was in the final stages of an interview process with other companies. They made me do a kind of IQ test (pattern recognition), which just seemed lazy, but whatever.

Then they booked two Skype interviews to be done on a morning one full week later (!!!) – one with an engineering manager (talk) and another of a technical nature (implementing an algorithm).

By sheer unluck, Skype had constant outages, so I couldn't do the first interview. When I got to the technical interview, they had it all ready for an Erlang code session, which is a language that I have never ever written a line of code with. After explaining that to the interviewer, they scheduled another (Java) interview for a week later. Their HR sent me emails with contradictory dates for the interviews.

I was informed that I'd do the two interviews on that same day. I actually got to do my technical interview, which seemed alright, but it seems they completely forgot about the other one. By that time, I already had a good offer on the table from another company and was pretty much convinced that they are really unorganized and incompetent.

I informed them that I already got another offer and that I did not want to continue the process, and guess what? They never answered back.

Would not recommend.
