I'm glad you explained that 'senior' pharmacist title. I didn't like it, still not crazy about it, but it sounds more in line with what you are qualified to do. That's being honest, not critical.
I worry about your team player skills. I like a lot about you. However, this need to out verify scripts and outperform, by large multiples, the other pharmacists is DANGEROUS. Not in an med. error way, but in a personal way. The fastest way to put a target on your head, is by out doing everyone else. It makes the others look bad and they will gun for you. The director will 'pat you on the back', but will become concerned for his own job security. Slow down. Let the world appreciate you, don't tell them how great you are.
Pulling out a phone to watch porn or play porn games at work is a big NO NO. Pharmacy is much different now versus when I left. There are no books in the pharmacy, NONE. Pharmacists pull out phones to look things up. I hate that. I don't know how to do that, I have no interest in learning, my phone doesn't offer web services and I never carry a phone. It burns me when I need to look something up and have to ask someone to do it for me. Work at a good pace, to appear busy. Never pull out your 'phone' and 'play' with it in the pharmacy. Handle your 'business' in the bathroom.
What I really don't like about the new position is the number of pharmacists and techs. 5 and 4 respectively for overnight, that's a lot. That seems like too many and normally there are more techs than pharmacists. This isn't a union position, you said. It sounds like a budget maneuver to get funds into the pharmacy. Creating 1 central pharmacy, is much better security than 4 satellites scattered throughout the hospital. If you are already working there, your not. Last hired, first fired. They have 3 positions available? (the one your going for + 2 others) I don't trust that from an employer, something's amiss. Sounds like cherry picking or they want lots of people around to make the transition seamless. People pay hookers lots of money for short periods of time. I'm seeing a street corner with your name on it.
Your sure your present employer can't find out about your interviewing? Make sure. Years ago, I changed jobs, 2 to 3 times a year. It was fun, easy and profitable.
Your licensed what, almost 2 years? Frequent job changing is now, not as advisable as it was, in the past. You better have a good answer when asked why are you wanting to leave your job of < 2 years. Don't dare say, you hear the pharmacy your at, is in financial trouble or you've always wanted to learn about peds. Practice and prepare, good answers. The newer position sounds dreamy. Aren't you in the NYC metro area? Lots of schools and pharmacists, I'm concerned at why such primo jobs are hanging around for so long. Wasn't this job brought to your interest from a head hunter?
Best of luck.
