One of the most common problems facing interviewees is themselves. Many interviewees have not thought enough about who they are and what they want out of life.
The complex stuff: What are your strengths? What are your goals? Who are you? what do you want out of life. You cannot squeeze preparation for an interview into the night before. Nevertheless, the night before the interview is a good moment to review your application, curriculum vitae and your general notes on the particular company and sector.
It’s always better to ask questions than to answer questions. But you have to know an interview is also stressful situation for the interviewer. If there is one and only one thing you do in your interview it should be to smile. Relax and have fun. An interview is a chance to get to know an interesting person.
It’s okay to say, “I don’t know, but let me sketch out how I would approach this situation/challenge/problem/opportunity…”
“Conceal a flaw and the world will imagine the worst” (Marcus Valerius Martialis)
And last but not least: the interview is also an opportunity for you to really assess whether this organization is the place for you. Good Luck
