I applied online. The process took 2 months. I interviewed at OptimoRoute
Interview
In total there were several interviews and a test. The test wasn't difficult, however it took quite some time. Experience rated as negative simply because after investing so much time and effort, one would expect at least some kind of feedback from them, which didn't happen.
Interview questions [1]
Question 1
The last interview, which was with founders, was quite tense. Questions weren't hard but after the founders introduce themselves and their accomplishments, it's easy to lose self-confidence. Don't let that discourage you. Other than that, they seem like a good company.
