First online test on HackerRank. I'm not sure how large the question pool is, but if you haven't been practicing problem solving you might struggle. I practiced so it went well. The second meeting was with HR - kind of soft skill testing nothing unique about it. They just want to check if you are reasonable person to work with. There was a meeting with developer later on. HR said they only hire the highest calibre developers, but after meeting with developers I really doubt that. They were lacking knowledge about Java and certain technologies themselves. The offer was really poor. It was remote so it is only a good offer if you are working from very poor countries and you have no means of living/working in Europe.

There was an online assessment and a phone call with HR. After that two technical rounds and a final interview with the project manager. The online assessment was easy to complete, HR meetings was not a real round but very helpful to get to know about process and company.
