Everyone one of us wants/needs to stand out when we get a coveted in-person interview.
Homework: Use Google to do some basic research. What exactly does the company do, what is there product? Where are they Headquartered at? How many employees? How many different locations do they have? And often you can find out has any of their jobs already been outsourced out of the country, or even to other companies. What are their short and long term goals? Most of this information can be hunted down in less than 1 hour of your time.
Look at Glassdoor, Indeed for what others have said about working for the company, those sites also will give information about the companies benefits. Like Medical, Dental,.Vision, 401K, vacation time and so on.
You want to have as much knowledge as possible before you start the interview.
Another part of what I call Homework and most people skip this part. Are you doing mock interviews? So you are not saying um, hey, yeah, ah, well, A few will not kill off an interview, but if you are doing all through the interview, guess what? They can tell you did not prepare. And there will be other candidates that did.
Mock interviews, get some questions from the internet, I am sure there are great ones right here on jobcase. You want to be able to answer the questions with a smooth delivery. Which will show you know your stuff and are confident. Oh and keep answers brief and on point. If they want more information, they will ask probing questions. Do not drag on for 5 minutes, answering every question.
