The interviewer all were nice. The process was really quick. I applied from their career web on Friday and I got invitation to to math test on the next Friday at 10 am. The questions were pretty hard for me. I got HR interview invitation on the same day (Friday at 1 pm). On Monday i got interview invitation with user for the next day (Tuesday at 10am), and also the Gdoc test on the same day (Tuesday at 4 pm). Unfortunately, the user is not compatible with me, so they try to move me to other user. I had user interview again on Wednesday and I got an offer on Thursday.
