I applied online. The process took 2 weeks. I interviewed at Insider One (Istanbul) in Nov 2025
Interview
First, HR asked casual things. After that they sent you a homework. After that, a team leader asks some technical questions. Lastly, head of teach asks more difficult technical questions. They were nice and supportive. They explain everything you need and answer all of your questions. They are so clear about expectations.
They gave a task of coding a ping pong game with Vanilla JS. They said I should only use pure Javascript and no other libraries or etc. There are some rules like the size of the game canvas and etc. and you need to complete it as they want.
