In the interview: DO ask questions.
In her article ‘Don’t ask that: dumb questions to ask in an interview!’ By Stephanie Castellano she claims people ask questions that are ‘dumb’ in her experience they are things like …
“How late do you consider too late for showing up to work?” 
“When can I retire?” 
“Can I take a three-week vacation?” 
“When can I get a raise?” 
So DON’T ask those questions!!
Instead DO ask …
“What is a typical day like?”
“What qualities would make someone successful in this position?”
“What do you like most about working here?”
“Who was in this position previously, and why did he or she leave?”
DO ask questions that could give you valuable insights into what it’s really like to work at a particular company:
Stephanie says ...
“When first meeting with potential employers, it’s better to pose big-picture questions so you can
discover how aligned your skills and personality are with the role and the organization… You can delve into the details in future meetings.”
DO ask questions, practice them first with a trusted friend and work out whether they’re DO’s or DONT’S. Sometimes we just don't realise the question may not be well perceived that's why practicing is so important to do with someone you trust.
Do you have someone to practice interviews with? Have you ever asked something that was not well received?
