8. Selecting a job very quickly: Selecting the desired job quickly is also one of the mistakes jobseekers make because when anyone select a job immediately just because they have been offered, they might go wrong at that time because they might have no idea what that position need from them or what are the qualities that they must have to be successful in that job. SO, instead of selecting any job that has been offered to you immediately, consult some people who know about the nature of that job, how risky it is, the benefits you can have from that job etc.
