You just stepped out of the interview and you believe things went pretty well. How long can you expect to wait to hear back from the employer? In most cases a lapse of anywhere from one to three weeks is common. It is important to remember to get an idea from the hiring authority of when you will hear back from them before you leave the interview. After the interview, if that time passes, a polite follow up is advisable to ask whether a decision has been made or not.
A common problem for job seekers is waiting to hear back for the more attractive position or having several offers to choose from at the same time. It is acceptable to ask for time to consider an offer that is given. Of course the time frame must be within reason. Most hiring authorities would agree that they would rather give the candidate more time to make the right decision than have them quit in their first week because they acted in haste.
There is always pressure for a job seeker to accept the first job offer they are presented with. Review all your options and evaluate whether or not you can continue your search at the given pace or if you must accept the first offer. Only you can decide whether or not a position is the one for you, but it would be beneficial to talk to friends, family and peers to see what helpful advice they might have. Remember, accepting a job offer is an important decision which should be carefully considered.
