Really, really bad experience. Didn't receive any feedback, recruiter went silent after reaching out (would not even respond to an email on updates), and saw job was reposted on LinkedIn. Really unprofessional, interview was easy as well and was told I would be meeting other members of the team. Downright pathetic. Wouldn't apply here ever again.
