Chances are at some point you will have to face some sort of rejection from a recruiter, but it is how you deal with this rejection that sets you up for your interviews for future jobs. Criticism can be a good source of useful information, as long as you can take it on board and learn from it.
If you receive, or do at some point in the future, a rejection from a job application always ask for feedback. It doesn’t matter what stage of the process you are rejected at, always request the reasons behind their decision. Once you have this do not let it negatively affect you and your motivation, instead use it as an excellent means of improving.
Now that you know what your stumbling block was you can set actions in place to resolve it, whether it is something on your CV or perhaps even something you said during an interview.
Criticism can definitely be a worthwhile lesson, just make sure you take the good from the bad and move forward.
