Recruiter contacted and asking interest to the position and 2 onsite interviews, 5 video interviews was proceeded After even I've got the green signal from last interview and thier review on my background, they suddenly informed I am not relevant for the position This was very inappropriate and unprofessional hiring process. Be aware of twitter's offer if they made the cold-call to you. I would not recommend Twitter for the new job. they have totally no credibility for hiring and treating the candidate
