You will generally receive a response from the hiring company or the human resources department a week or two after the interview, but the waiting time varies by sector. The amount of time from interview to job offer varies. For college graduates, the National Association of Universities and Employers (NACE) Recruiting Benchmarks Survey reports that employers who hire new college graduates take an average of 24 days to extend a job offer after an interview. However, on average, you should know if you've gotten the job or if there are signs that you're going to get it within two weeks of the interview.
You can't change the fact that it often takes a long time to get a response after an interview, but you can control the number of jobs you apply for. So, while it's always possible that you'll receive the job offer after waiting a few weeks, you really should keep applying for more jobs and arranging more interviews. The hiring process can vary from employer to employer, the type of job you apply for, and the industry in which you work. It's always a good idea to leave the door open to re-apply to a company after a job rejection and maybe you'll get a job that works better for you.
The job offer itself can also be delayed or rethought based on internal company problems (this can be due to changes in management, the budget, or a change in the person who leaves the position vacant). The reasons can range from the obvious (you didn't get the job) to something as simple as the employer's schedule (they're on vacation). After the in-person job interview, the hiring manager often needs to meet with several members of the team to discuss your application. The job offer is followed by a review of the applications submitted, which can be processed by an applicant tracking system and then reviewed by a hiring manager.
They should also contact human resources and other departments before offering you a job. If, for example, they ask you about the salary or the equipment you might need for the job, these are signs that you are going to receive a job offer. Try not to read too much about how things have been going, especially if it's been weeks and you haven't received a response after a job interview.
