When job searching, there is an important truth to realize. Just as much as you want to be picked by them, they are desperately hoping that you are the right candidate as well.
I think many job seekers forget that fact. The people trying to fill the position are hoping that every resume, every interview brings them one step closer to finding the right person.
So relax.
Remember this as you start your next interview. Make yourself open to showing them if you are or aren’t the person they are looking for.
