In life, little things can become big things. In job search, little things are the big things. Last week I described some big mistakes that job seekers make and asked you to compare them to the do’s and don’ts you’ve been practicing.

Here are a few more, just to keep you thinking:

What to wear: How to dress is a matter of concern to many interviewees who ask what they should wear if it’s casual Friday (or Monday, Tuesday, or Wednesday) or if their chosen workplace doesn’t seem to care what people wear. Play it safe: Whether you’re on a formal interview or informally networking, respect the person who’s taken time to talk with you about your career and dress professionally. That suggests that you are well groomed, clean, fresh, pressed, jacket and dress slacks for men, suited skirt or pants-suit for women. If you wear jewelry, keep it simple. If you smoke or wear a fragrance, air-out. No sense triggering an asthma attack.

Thank you letters: If you send one (a good thing to do) make it work for you. Thank the individuals involved for taking their time to discuss with you the key challenges facing their organization and the role you can play in addressing them. Reiterate your ability to make an immediate difference and your strong interest in the position.

“This is a job I can do and want to do for you and for your company and I look forward to hearing from you.”

Develop a solid close: Most applicants spend so much time worrying about the front end of the interview (what will I wear? what will I say? what will they say?) and what happens next (did they like me? will they call me? should I call them?). that they don’t think enough about the importance of patience, pacing, listening, asking open-ended questions, overcoming objections, responding strategically, and asking for the job.

Negotiation: You haven’t completed your interview prep until you know the fair market value for what you bring to the table. In other words, what’s the going salary for people with your education, experience and track record, in your geographic area, for the position you want and the accountability that accompanies it? Once you know that range, you’re ready to discuss their offer. If it’s lower than what you can reasonable expect, you have room to negotiate. Don’t know how? Try something like this:

“Mr. Jones, I appreciate your inviting me to be part of your team and I’m excited about going to work for you. It’s a job I can do and one I want to do. The only thing that keeps me from immediately signing is the salary. Given my experience, track record of accomplishment, and the accountability that goes with this position, the offer is less than I had anticipated. Can we continue our conversation? If not today, then tomorrow?”

Then sit quietly and patiently and let Mr. Jones respond. Both of you need time to percolate so don’t rush to judgment. Chances are, you’ll get an offer that’s better than the one that’s currently on the table.

Show up: Whether you know it or not and whether they tell you or not, you’re on probation for the first thirty to ninety days that you’re on the job. If you interview over your head, saying you can accomplish great things based on your history, and your history’s bogus, you’re going to be history.

Bottom line, tell the truth. Do an honest self-assessment and find a job that requires what you do best, not what you do least well. Focus on what you know; what you enjoy doing, and what you want to continue to develop through experience, training, and education.
