The process was messy and not as described on their website. I had a first HR call, then I was given a challenge and then I had a call with the product designer. After that It took the HR 2 weeks (and multiple followup with no response) to get back to me. I was already demotivated after this to say the least, mostly because out of principle I do not go with companies that dont respect people’s time and efforts.
Seemed like a good opportunity at first sight, a pity for the rest.
