The entire process took around 3 months. A first explanatory call about the position with HR occurred, then one call with the manager where we discussed my current role and background.

After some days, an assignment was given to me, which involved developing two small software tools. I submitted the code as agreed after a few days.

Then, they vanished.

They resurfaced after 2 months, asking me for a face-to-face interview. There, I met HR, the manager, and technical staff. The latter asked me some quizzes and technical questions, and also focused on the work I had done in the assignment. The whole process took almost 3 hours.

It was a very friendly procedure, with the technical staff being very nice and polite.

Finally, they vanished again, without ever providing a single line of response in an email, or even a call, or anything explaining the rejection or what had happened.

I would conclude that it's an extremely amateur process, and I regret spending time on it. It was totally not worth it at all. There are plenty of serious companies that may not be as big as this one but respect you better and are, of course, better organized. Much better.

If they treat you like this beforehand, I'm curious how they'll treat you afterwards.

Quizzes regarding string manipulation, sorting, etc. Also, questions regarding the code I've written and my approach.
