Never show a sense of inferiority in any situation. Inferiority is the most expensive and unprofitable state in this world. Any place you can enter already proves that you are qualified. The so-called "I don't deserve it" is just you putting a mental shackles on yourself. It might cause you to ask for 30% less salary during an interview, dare not look directly at the other party at the negotiation table, hand opportunities over, subconsciously take a step back in front of someone you like, and watch fate slip away. The most frightening thing about inferiority is that you send a dangerous signal to the world with your aura: I am not important, you can treat me arbitrarily.
