Proton, privacy by default Java/Scala Developer interview questions

The process took almost two months... Classic HR questions on a phone call -> Long tech task -> 4 hours interview with the team. In case you are working, I think it's "difficult" to find a slot for 4 hours to have this final step with the team. However, it looks like they made decisions based on the knowledge you have about some libraries. Another whiteboard tech task that you should solve is as they want. They said in two days we'll get back to you with some feedback, but I had to send two emails, one email every week of delay, and then I got the feedback, but the email just said that they have a lot of applicants, so they decided not to go further. I recommend you to read the book: "ask me this instead" they were not able to reply some of this questions... so can give you a little bit of idea about management probably. It's been a waste of time, and energy.
