I applied on Linkedin , and was called by someone from HR deparment. After a tehnical interview the same person called me and told me that the feedback from the team leader is positive , and asked me for a day when I can have a meeting with hiring manager . After a week a asked her if something happend because I didn't get a response to scheledue the meeting, told me that she did't receive the availability from the manager. After 1 month ,I got a response that they decided to go forward with someone else. It seems totally unprofessional for me
