I went through 5 rounds of interviews (HR, Gallup, Senior Manager, Hiring Manager, Future Colleague). I received an offer where the salary was significantly lower than initially agreed to. Apparently the recruiter had ''made a mistake'' in the first call when discussing the pay. It was very disappointing and I had to turn down the offer. What a waste of time for both parties... Besides this major error, there were in general quite a lot of mistakes made by the HR department throughout the whole process related to scheduling and location mix-ups. As for the interviews, they were comfortable. There were no unexpected questions. The Gallup interview is the only one that I would describe as more complex as the questions are quite diverse.
