Some things should never be said―like these phrases. Here, what to say instead.
Don’t say: “My current boss is horrendous.”
Why: It’s unprofessional. Your interviewer might wonder when you’d start bad-mouthing her. For all you know, she and your current boss are old pals.
Instead say: “I’m ready for a new challenge” or a similarly positive remark.
Don’t say: “Do you think I’d fit in here?”
Why: You’re the interviewee, not the interviewer.
Instead say: “What do you enjoy about working here?” By all means ask questions, but prepare ones that demonstrate your genuine interest
in the company.
Don’t say: “What are the hours like?” or “What’s the vacation policy?”
Why: You want to be seen as someone who focuses on getting the job done.
Instead say: “What’s the day-to-day like here?” Then, if you’ve really jumped through every hoop and time off still hasn’t been mentioned, say, “Can you tell me about the compensation and benefits
package?”
