I applied online, the week after that we had a meeting in the office. It was technical interview, mostly about c++, and I had to explain few lines of code, but overall experience was nice, because atmosphere was relaxed (there was also small talk about sports, some jokes, etc.)

I had six rounds in total, The first round was an online test followed by four technical rounds and then finally a culture round. I found the interviewers to be very warm and patient with me, A very good experience overall.
