First step was to receive a contact from an external recruiter and join a 15 minutes call where it was explained what they expected and I mentioned my overall experience. I've mentioned I didn't have specific experience with mobile native apps, and was told that should not be a problem. I asked him to submit my CV to Bumble and mention that, and it seemed that Bumble team was ok, really quickly they sent me an "Online Test" very specific to Mobile applications that I was able to finish anyway, but obviously not nailing on details. After that I got absolutely no contact from the company for more than a week, I'm assuming I wasn't a good fit (not a problem, I was really out of my confort zone), but I'm really sad with the lack of information, that tells me a lot of the company culture and how they treat their employees, felt like joining one of those terrorist processes from 90's when applying the big corps.
