There are 4 or 5 stages. I did not get through all the stages. The first interview was a simple screening where I got asked questions like why their company, why that position, why their industry. Then there is an interview with some managers/senior people, team and also a case study. The last interview should be with the board. They kept talking about how fantastic culture they have etc. Stay away from this company... probably the worst interviews I have ever had with really unfriendly and sniffy people.
