Questions d'entretien chez MainSpring

I've had three rounds of interviews with them, and in the end, they didn't hire me. While I'm glad about that, I really dislike it when people are polite throughout the interview process but then disappear without any communication, not even an automated email. I wouldn't recommend them, and they really need to improve their communication.

IQ test that to be answered in the first session like pattern questions and then asked to introduce myself. Overall the interview takes 2 hours cause we most likely discuss rather than interview itself. I interviewed by one person.
