FareHarbor Key Account Manager interview questions

The talent Acquisition Coordinator got in touch with me via Linkedin. I am already working so I was not looking for a job. The process was 4 interviews: first over the phone, second in their office (1.5 hours) met 5 ppl, third a written test, last a play role over the phone. I did also a personality test before meeting them. They seemed very interested as they asked notice period, leaves planned etc.. After 4 interviews and a personality quiz, time spent to do their test and found time to speak with them they sent me a very interpersonal email template saying I was not the right candidate ...The minimum would be to call me and give me a constructive feedback especially as I didn't apply they asked me to come! Time wasters for sure.
