Five recruiting professionals share what interview questions they always ask candidates.One favorite question identifies proactive leaders who drive business results.Recruiters say an ideal answer to a question about when something went wrong with a project identifies what was learned.Another question about what a candidate needs in their next role can open an honest dialogue about values and goals.Interviewers like to open conversations with the classic icebreaker, 'Tell me about yourself.'Also popular is asking about a candidate's greatest impact and what helped them achieve it.An ideal answer should be authentic and real, not the answer you think the interviewer wants.Answers can determine a candidate's problem-solving, ability to communicate, and willingness to take responsibility.Candidates should use the STAR method (Situation, Task, Action, Result) to answer.Recruiters also want to know if candidates stand up to additional questioning well.
