I applied in-person. The process took 4 days. I interviewed at TGT Oil (Kazan) in Jul 2015
Interview
Found a vacancy on hh.ru and emailed them. Had an phone call with HR, then - in-person interview with HR and team leads (all-in-one), it was very simple (no tricky questions). After that they suggested me to complete a home assignment with two simple tasks. One - on data structures and one - on math algorithm implementation. I completed it successfully, after 2-3 days I got an job offer.
Interview questions [1]
Question 1
Very basic questions about technical skills - what is your technical background, have you developed with QT, are you able to understand basic physics theory stuff etc.
