It started with a psychometric a test which was quite simple. They are just trying to find out your general personality. Once I passed this one, they have scheduled a phone interview with two directors of the sales team for a STAR behaviour interview which took 1,5 hours. I suggest to be properly prepared otherwise you won't be able to come up with so many different work situations for different challenges, achievements etc Remember exactly how you handled difficult situations with clients and colleagues and what your biggest achievements were from your previous and current roles
