It's a very good leverage and a great credential a master degree is specially if you're aiming for good rank in a company you're applying for. A master's degree is also given to a person who actually 'mastered' a certain program. This gives the company the confidence that the person they will be employing actually knows what he/she is doing.
Too true, a master's degree is a solid leverage for companies. But some actually value experience more than how long you actually studied your classes. If i had a company, i would actually value experience. It actually at some point equalizes the opportunities and i would advance them by due of merits.
