All kinds of goofy things happen in interviews. Crazy questions. Bluster. Fluffed up claims of accomplishments and skills……etc.
It’s a good idea to put yourself in the interviewer’s shoes. Ask yourself what they want. What the interviewer wants is to hire someone who will do the job they need to fill really well. To make an impact on the company and to make the company better, more profitable. If you can’t do that the interview is pointless. If you can do that, you just need to show them that you can and will.
