I applied on LinkedIn to two similar positions. Never heard back about one of them, but contacted by a recruiter about the other one after a week or so. After that she stood me up three times over the course of two weeks. She assured that she would call me at a certain time, and I had to take some time off my current work to accommodate the call. However the call never materialized. After a fortnight, she finally kept her time. Gave me some background about the company, and said that she would forward this to the hiring manager. It's been a few weeks and no response yet.
