Entrevista
Phone interview - fairly standard software dev and HR questions.
Face to face interviews - 4 interviews with 2 interviewers in each and 1 "bar-raiser" interview. 45 mins each. Very little break in between and ran over my lunch break, so didn't have any lunch. Also, didn't get to see any of the office and was abruptly shown to the door after the last interview as the HR person wasn't there. Didn't have a good impression of the company from the interview process.

Online Assessment is the first step in the process. I didn’t have an HR phone screening and went straight to the OA after applying. It was sent to me about a week after I submitted my application.

Unit tests must pass to pass the second question. You can run both backend/frontend indivdually or together
