Dear Glass Door user, There could be few reasons that could result in an job offer being revoked. The top reasons could be 1) Background verification failing 2) Candidate not joining on the committed date resulting in that project getting cancelled, postponed or being staffed by another candidate We are very flexible with interview slots and accommodate the candidates preferences most of the time. Unless the prospective employee is comfortable with a particular timing, we do not force them. Looking forward to work with you in near future. If you are still looking for a job change please contact our HR team and we will definitely consider you for any suitable opening at this point.
