10 Reasons They Haven't Contacted You After a Job Interview:
You had job interviews at a place you'd like to work. The interviews seemed to go well. Maybe one of the interviewers said they looked forward to working with you. But, not a word from them since then.
The recruiter/HR person/hiring manager said they'd make a decision before the end of last week. Or by the middle of last week. Or before the end of last month. Or some other time in the past. Their own deadline has passed -- maybe days, maybe weeks ago. But, you haven't heard from them. And, you may never hear from them. Or, you may hear from them tomorrow...
Don't "pause" your job search while you wait for an answer.
Do NOT put your job search on hold while you wait to hear the news on any job! Keep your job search momentum rolling. Until you hold a job offer (with the right job title, salary, and start date) in your hand, you don't have a new job.
But, don't assume that no news is bad news for your job search!
You will probably not be told what happened, but don't give up on an opportunity too soon. Employers almost always need more time to fill a job than they believe they will. Particularly if it has only been few days or a couple of weeks past the date the employer said they'd get back to you, don't give up on the job. Yet!
10 Things that Could Be Happening While You Wait
Job seekers always seem to assume that the process works perfectly and smoothly on the employer's side. But, speaking as someone who has been on the "other side" of the process, that assumption is often totally wrong. The reason you haven't heard from them probably has little to do with you. Or it could have everything to do with you.
Without intending, the employer's plans for the timing of the next step in the hiring process are almost always too optimistic. Many things can disrupt the schedule, particularly in large organizations.
