I received an email from a recruiter to set up a phone screen. I never received a phone call, so I reached out but no response. The next day the recruiter apologized and rescheduled. After we spoke I was invited to come in for an in-person interview. The recruiters we very friendly and informative. I was invited back for another in-person the following week. Same thing. A few days later, I was invited to Skype with the manager. After that I was invited for ANOTHER Skype with the head of the department. A few days later I received a link to complete a background check. A few days later I was notified that the background check was complete and I had passed. About a week later and I had not heard from the team. I reached out looking for a response and they said they have not made a decision. Another week went by and the same thing. It took about 3 weeks for them to send me a standard rejection letter after I called and emailed multiple times. I was extremely disappointed because of the extensive interviewing process. No explanation and no apologies. Very unprofessional.
