Telephone interview about your skills and experience and also about the company then a competency based interview regarding dealing with a customer query via email and a face to face interview

The whole process was way too long. I applied end of August and HR contacted me via email to answer some questions. The next stage was a task where I had to answer customers' reviews and emails. The final stage was a video interview with couple members of the team which I had in mid-September. The interview was long and felt more like an interrogation than an interview. I received an answer in the beginning of October but by then I already found another job.
