Had a standard 30 min screening call with team leader, did a simple take-home task. Then there was a code review interview, then there was a system design session, then there was an interview with the CTO, then a culture fit interview, then I received a standard rejection letter with no explanation.

The interview process consistest of four stages: 1. Interview with HR, where they get to know you a little bit and you get to ask questions about what does 3D hubs do, etc. 2. Interview with two elements of the engineering team, where you describe your experience and they ask questions about what you did, problems you had, what you most liked to do and why. They were very nice and it was a very chill conversation. 3. If the previous interview is successful you do a test, which you have a week to finish if I'm not mistaken. It was a web app where you could play the hangman and you have to implement the guess function, do tests, etc. It was easy IMO (I'm a junior). 4. After that, you have one interview where you discuss the test and your choices, it was chill. Also, you have an architectural interview where they give you a problem and you need to design the system for that problem, i.e., which database would you use, the data model, the communication between front and back-end.
