My experience was extremely poor, but it is hopefully just because of the in-house recruiter I worked with.
She asked for my availability for a phone screen on a Friday. I submitted right away. I heard back from her at 10:30pm on the following Monday, scheduling me for a time on Wednesday. I emailed her right away to let her know that a professional conflict had come up and tried to reschedule. I then emailed her the day of - and she never responded to either email, but called me during my meeting.
I had to miss the call, but she left her number, so I called her back and left a message, then emailed her three different times. She finally responded on Monday to schedule for a time on that Wednesday.
We chatted about my experience, my skills, and my interest in the role, as well as a deeper dive into all that the role entailed. She told me she'd have to wait to discuss my candidacy with the hiring manager the following Monday as the hiring manager was in a sales training until then. She said she'd let me know next steps following that discussion.
I emailed her on that Tuesday, and I have never heard from her.
My main maddening frustration with this is that this is Glassdoor, the company with a foundation of reviews - not just on culture, but on the interview process as well. As a company that situates itself within the employer-employee-job seeker dynamic, this review of a recruiter as a representative of what you should know about Glassdoor is something they literally ask for.
I would generally love to see the interview process become more considerate of the job seeker, active or passive, but based on my experience with Glassdoor, it's not happening here.
