It is true, and not that I am trying to be dishonest myself but I am not the same person while taking an interview. It's a sad that we can't be honest or humble but in this system we have to sell ourselves, fake enthusiasm for the hiring company is a must, do whatever it takes to pass the interview then think later if we take the position or not. If not, somebody else with the same capability or or less will snatch that job. Plus that interviews like tests are gameable.

In an ideal world a trial period would ensure both the employees and employers are a fit. But that could be abused as well if it becomes the norm.
