Only one interview with their CTO via Skype. tl;dr: interviewer was in a rush to finish the interview; zero interest on presenting the company; focused on asking questions that you can give memorized answers; rude behavior. First part of the interview: as soon he knew I could hear him (10s after the call started) he spoke non-stop at 1.5x speed for 5 minutes about the company’s main products, what they do and their business model, using terms that belong to their business. If you have never worked with Ads/campaigns/etc, look for it first or you will end up like me: hoping he doesn’t ask anything about what just dumped on you. Second part of the interview: time to introduce yourself. Third part of the interview: reading a script, he gave me basic questions about Java keywords, multithreading concepts and data structures. Get back to your books from CS101 and I’m sure you will have a better interview than mine. Due to his professional manners during the interview, I would never work for his company under his management. Good luck for you.
