Keeping my fingers crossed that you hear some good news!
Those are pretty much the standard interview questions. Research other questions and think of your answers to them ahead of time. ALWAYS research the hospital and know their mission statement. What about their accomplishments? Use that information to help answer the "why do you want to work here?" question. Don't just tell them because you need a job! Is the hospital on the list of the one of the top 100 hospitals in the U.S.? (or even better, the top 10?) Do they have Magnet status? Did you have clinicals there in the past (maybe say you had a clinical rotation on X unit and you were impressed with the team work and positive morale on the unit, and that you would love to work with a group of fantastic nurses that work on that unit!) Regarding strengths and weaknesses, have at least 3 of each prepared. Try to turn your weaknesses into a strength or show how you are working on your weaknesses. For example, maybe one of your weaknesses is you don't have much experience. Turn that into a strength by stating you can gain that experience with this position or talk about attending educational seminars, etc. Don't tell your potential employer that you have no weaknesses, that's a big no-no.
Regarding conflict with coworkers...I have never really experienced a "conflict" per se, but I have experienced internal conflict. There might be something about a coworker that I do not agree with...even if they are doing their job correctly and safely, I still have that "internal conflict." I told the interviewer that I still maintain my professionalism - I don't treat the coworker any differently from other other coworkers, don't talk back to them or belittle them, try to offer them help, etc.
Situational/behavioral scenarios can be tricky...just go with your gut and try your best. A lot of my questions were based on dealing with mean doctors/patients/visitors. Again, maintain your professionalism...apologize for any delays, try to find out information and get back to them as best as you can. Don't talk back to them. And as always, if you're not sure of the answer, seek out help from other coworkers, the charge nurse, consult policies/procedures or consult your immediate supervisor.
Hope this helps some. Good luck!
