Q:

So if md5( ) generates the most secure hash, why would you ever use the less secure crc32( ) and sha1( )?

Answer Crypto usage in PHP is simple, but that doesn’t mean it’s free. First off, depending on the data that you’re encrypting, you might have reasons to store a 32-bit value in the database instead of the 160-bit value to save on space. Second, the more secure the crypto is, the longer is the computation time to deliver the hash value. A high volume site might be significantly slowed down, if frequent md5() generation is required.

Q:

How do you handle stress?

Answer

How do you handle stress?

Wrong approach -
Do not say you are never under stress or I hate stress or you do exercise and meditation to take care of stress. Focus strictly on professional things that you do.

Right approach -
A good response is to say that pressure helps you focus and maintain your drive and like to handle challenges. Explain that some of your best efforts are the result of stress and pressure. Also inform that when pressure gets too intense, you know how to handle it.

Example -
Stress and pressure are a challenging part of the job and i know how to handle it. I handle it by focusing on proper planning and reporting, better time management, open communication, Hard work and prioritization.
