What I'm about to share is from the perspective of an employee seeking a job (non nursing; I've applied to nursing school recently though) as well as being in a position where I made hire decisions.
1. Never give up.
2. Always learn.
If you had an interview, review in your mind and go over how the interview went. While you cannot go back in time, think what you need to remember to do differently next time. What can you improve? What needs to change?
3. Whenever you get a an interview, if you've made the decision you want to work for the organization doing the interviewing, let them know at the end of the interview you want to work there.
4. If you had an interview, always send a thank you follow up letter via regular mail.
In the thank you letter, thank the person for their time using their name (did you grab a business card or otherwise write down the name(s) of the person interviewing you), let them know the key points you got out of the interview.
Then list two to three reasons why you believe you are the right person for the job.
End with your hope to hear from them. Be sure to include that you will follow up with them within x period of time where x should be two weeks or less.
Of note, if you don't want the job, still send a thank you letter; but leave out why you are a fit for the job portion.
5. Follow up.
If you didn't get an interview, follow up asking to have an interview.
For key places you want to work, follow up multiple times decreasing the number of follow ups over time. I.e. start off following up once a week for x weeks, then once every two weeks for y weeks, then once every four weeks for z weeks.
6. If you don't get the job, BUT really wanted to work there or are just ... hmmm... I should have at least gotten an offer, call the person who interviewed you, thank them for their time... and now the tricky part... let them know you don't want to change their mind, but could they share why you didn't get the job as you are trying to grow and improve.
While most will either not take the call or just give you kind words (that are lies rather than tell you how it is -- blunt), you will get the occassional person who will give you enough information so that you can learn, grow, and improve for the next interview.
7. Keep track of everything -- dates for sending out applications; date, time, location, person's involved in the interview plus notes you took during the interview; follow up means and results, etc.
Now from the employer hire side of the fence.
* Thank you letters always impressed me. The person valued my time; the person really wants the job.
* How confident was the person during the interview?
* Did the person come across as being honest / a person of integrity?
* Did the person blabber -- T.M.I. (too much information)?
* If I asked hard questions, did they jump on those or give pause or fumble?
* Where they passionate during the interview? Did they show passion for the job?
* What did they dress like? Where they professional? Did they dress like they were going to a party or a date vs. an interview?
* Why should I hire them vs. x number of applicants? What made this person stand out?
There's more... but as you interview... remember human is human. We are all equal; be respectful and kind. Be yourself (hopefully that includes being respectful and kind).
