Applied to two different R&D Associate positions, was invited to intereview for both. I was contacted by two different recruiters for each position and in the initial recruiter screen interviews, they told me that they were aware I'm being interviewed for two positions because they're in the same recruitment department. I passed the recruiter screen, hiring manager interview, and final round all-day interviews for both positions which included interviews with other people in the department, the hiring manager and the recruiters again. The day after my final round interviews with one position, the recruiter asked for six references, five of which will submit their responses through Skill Survey and the sixth will be contacted by a hiring manager. It has been nearly four weeks since I gave my references (and I confirmed with my references that they spoke with the hiring manager or submitted their responses) and I have not heard anything despite following up several times. This has been overall a very negative experience due to the ghosting and I am disappointed that the company dropped the ball with communication.
