I was taught that after an interview I should fill out a thank you card addressed to the interviewers, and pop it in the mail either as I was leaving the facility, or 3 days later. Then give them a week. It doesn't matter what THEY say. What matters is that you have a game plan for landing a job.
Don't ever fall in love with a job at the first interview. And ALWAYS have at least 2 other jobs on the line. Try to set up all your interviews in the same week so that you can feel polished and prepared. Have those thank-you cards in your satchel for each one.
Never divulge to them how much you want any particular job, but DEFINITELY let them know that you are considering other employers and make sure to tell them that you are only interested in seeing which employer is the best fit.
Best Fit is everything, and subjective to whim (IMHO).
The thing about the thank you card is to keep you fresh in their minds. Seriously. This works for me every time. They ARE busy and meet lots of job hunters, most of them qualified. Who will stand out. How can you stand out? This is one way, amoung several. The key things to include are WHo you are, How they know you, When they met you, what position you were interested in...
The Thank You cards should be sent separately to each interviewer, addressed to each one personally. If you can, send it to their home. If not, sending to them at work is fine. It should say something like "Dear XXXX, it was a pleasure to meet you. I enjoyed the interview on Monday June 1, and wanted to thank you for the opportunity to learn about working for XYZ Company ED. I hope to hear from you soon to follow up. Have a great week! Sincerely, ME, RN (Make sure your signature is legible)
1 week after you sent the card (I send my card as I leave the building so I can remember what day I sent it) if you haven't heard back from them yet, give them a call with additional references you thought they might like to have, and ask them if they have any additional questions. Ask them again what skills/traits/qualities they are looking for- and if you didn't answer the way you wished you would have at the interview, you have the chance now to say "I have considered what you said/Spoken with my mentor/spouse, or etc, and I want to let you know that I would be Happy to work nights/Float to TCU (whatever it was)."
Stay professional, and remember that the interview process is as much about selection for them as it is for you.
Meanwhile, go to your other interviews, and do the same thing. When asked where else you are applying, tell them if you are comfortable with it and see what they say. you might learn a lot about the other companies! COme right out and ask them how they compare.
Again,you are both looking for the right Fit.
Before you leave the interview, ask them for their business card (If you don't have one), and when the best time to reach them is. Write this on the business card. Ask them when they expect to be making a decision/when do they need the position filled by. Ask them also if they have a 2nd interview for likely candidates, and when might they be holding those.
During the first phone call with additional references, changes to your input, additional questions, etc... it's OK to ask them how they feel your interview went. If they said they had some concerns, tell them you understand. Ask what you can do to reassure them (If you feel their concerns are due to the fact that the interview didn't go well, or some extenuating factor).
... in any case, the main thing is to put yourself out there. Be the professional they want to hire and can count on, someone with follow-through. Keep yourself fresh in their minds.
When the date they expected to have hired someone has come and gone and you didn't hear back from them, for your own professional development and in case that person doesn't work out-- call them again.
Ask them what are the qualifications/traits/skills of the person they hired. Ask them what nudged them in that direction, and what you could have done differently. Thank them again, and leave the conversation giving them the idea that if another position should open up, that you would like to be kept in mind.
Hope this helps.
