What are the three toughest questions to be asked in an interview?

1) What salary are you looking for?

Most people will tell you that whoever answers this question first loses. But that's not necessarily true.

When an interviewer asks your salary requirement, try first to gently deflect the question by inquiring about the salary for the position.

If the interviewer presses you for a number, give a range. To decide on a range, think about the salary you want, your salary at your most recent position and the industry-standard salary for the job.

The bottom line: The salary question is one of the most important, so you should prepare for it in advance and plan what to say.

2) Where do you see yourself in five years?

The best tactic: Talk about your values.

Don't get too detailed about your specific career plan. Instead, discuss things that are important to you professionally and how you plan to achieve them. If growth is a goal, mention that. You can also talk about challenge, another value that employers prize in their employees.

3) Why should we hire you?

There's a fine line between boastful and confident. And you need to learn it.

When an interviewer asks you why they should hire you, you're going to have speak confidently and honestly about your abilities. But you should avoid sounding overly boastful.

Aim for earnest and prepare by practicing. That's right: Stand in front of the mirror and acknowledge your abilities and accomplishments to your reflection. Tell yourself: I have a very strong work ethic. I have integrity. I have excellent industry contacts. I aggressively pursue my goals.

It's sometimes hard to praise yourself, but after a few sessions you'll sound sincere.
