I applied through a recruiter. The process took 3 days. I interviewed at Esker in Nov 2015
Interview
First contact at a job fair, HackerRank test received in the evening. Completed the test immediately, got called for an interview the day after. Had to complete an online personality test. Onsite, one technical test, then HR interview, then technical interview. Total onsite time about 3h. Got called the day after for a positive response.
Technical test, interview with five persons if selected. Technical test quite long but interesting. Feedback with a potential future colleague. Interview in Panel, relaxed but intense. Scrum mode, collaborative traits, and personality are also assessed.
