First round was a screening interview. The second round was an interview with the head of the QA, which was very interesting with smart questions about skills and product.
The third round was a technical assignment which is expected to not take over 2 hours (according to the description), but in fact it is a lie.
The fourth round is a 4 hour - interview (seriously) with the team (technical session, qa mindset, testing competency and leadership principle). That's when I declined considering that, together with the time taken for the coding assignment, it would be over 10 hours. I am even get payed for that.
