J'ai postulé en ligne. J'ai passé un entretien chez Tango
Entretien
The worst phone interview I've ever had. The interviewer didn't even say hi and started questioning me right away. He didn't introduce either himself or a team he was working for. The style of asking questions was not friendly. Once I mentioned I'm a Java SE guy, not Java EE, he clearly lost any interest to me. At the end of the interview I wasn't offered to ask any questions. Instead the interviewer demanded that I sent him a piece of real code I worked for.
After the interview I didn't receive any yes or no response.
That was really really poor interview experience. The company clearly has no sort of traditions of conducting interviews and doesn't care about candidates' impressions.
A pure waste of time.
J'ai postulé via un recruteur. J'ai passé un entretien chez Tango
Entretien
A few phone screenings, which was followed up by a few Skype one-on-one direct interview conducted by actual engineers (your future coworkers :) ). The questions concentrated around writing real code and solving real problems (no textbook graph theory). If you want to get a job, you need to know your stuff - for backend developer it means multi-threading, REST, relational and NoSQL DBs.
Three onsite interviews. Most of questions involve data structures, distributed systems, working experience. Not too tough but need to be well prepared. The interviews make me feel good as they are not brain teaser interviews like other companies i interviewed.
