I'm a millenial. Going into an interview, I am SHITTING BRIX. Seriously. I am horribly awkward. I am bad at coming up with stuff on the fly from nervousness.
However going into that interview I am preparing as much as I humanly can.
Spiff up my suit + tie - regardless if they wear casual or not.
Go over common interview questions
Research the firm
Re-read the job description over and over and over and over to the point where I know everything they are asking for on it.
Arive to the location so early I have to sit in the car for 10-15 minutes in order to not be considered insane.
Yes, my generation is a piece of shit. No, there is no hope for them. Everyone thinks that high unemployment is from a bad jobs economy? No, it's from complete morons.
Relax. Be confident. That might mean wearing a suit more often than just for a job interview, just so you feel confident and comfortable wearing it.
You have the right idea on the job description, interview questions and all that, but you forgot one important thing. Your resume. Seriously, know it. Anything you write on there is fair game for me to ask about, and if it looks interesting, I'm probably likely to want to talk about it.
Now, have you done a phone screen with HR for this position already? If so, it means you did well enough to move on to the next round and interview in person. That's a big step, so take that as a victory.
I'm not sure what line of work this is, but be ready for the following:
1. Walk me through a past successful project
2. Walk me through a time where you helped resolve conflict that could have impacted a project
3. Tell me about yourself
#3 is the all time worst interview question on the receiving end, but I do use it. It's basically asking you to tell me what's important to and about you. If you're just coming out of college, telling me about how you became interested in your field of study, how it applies to the job/company and how it led you to this conversation are some good bullet points.
All I really want to know is that -
1. You can think critically about what I'm asking
2. You can communicate succinctly on the topic
3. You are capable of actually answering my damn question
4. That you are driven, enthusiastic and motivated to do whatever it is I'm interviewing you to do
5. That you have some sort of personality, preferably one that fits well with your potential coworkers
Obviously, the higher level or more specialized the position, the more we might get into the weeds on specifics. I don't think that applies to you yet.
