First call with HR very basic and classical questions. The second interview is with very junior product managers, One will ask you questions and the other ones just here to watch. I would say very basic questions, looks like they are just reading from a list of non sense questions about the organisation in your former jobs and are not really interested in your real competences. They must think they are the smarter person in the room, and think they work at google or something. Looks like they just want you to say what is written on their screen. Spoiler alert : It's not the case ! So they should be more humble in my opinion (and take a look at their product, which is far from perfect ...)
