In an IT interview, always try to be specific and concise.
There are some things that will wreck an IT interview faster than you can say hello. This post will expose some interview busters that you might not expect.
1. Dressing inappropriately
Yes, many jobs now allow employees to wear jeans and t-shirts to the office on a daily basis, but interviews still demand business attire. A simple business suit is always the best choice for interview attire, and many if not most IT interviewers will disqualify someone who shows up to an interview dressed too casually. Worse yet: for women, dressing sexy for an IT interview also sends the wrong message.
2. Being too general
Most IT managers are precise people, and they expect some level of precision from others as well. Telling your interviewer(s) that you left your last job because you "just needed a change" or that you want this job because you "need to pay the bills" will send up a red flag about your ability to be detail-oriented and precise at your job.
3. Giving very long responses
Nobody wants to work with someone who talks too much, so try to strike a balance between answers that are extremely short and those that just go on and on. Tell your story and give specific details, but avoid rambling and talking a lot without having much of a point.
4. Saying "I don't know" a lot
You don't want to leave an impression with an IT interviewer that you don't know what you're talking about. By answering multiple questions with "I don't know," you run the risk that the interviewer(s) will associate you with not knowing anything - which is not the impression you want to leave with them.
Honesty is important in an interview.
5. Bad-mouthing former company or boss
Bad-mouthing anyone or any company is always bad form in an interview, even if it is entirely justified and based on facts. You always want to talk well of your former company and boss; it's better to be seen as magnanimous than petty.
6. Not asking questions
Employers and managers want to know that their IT hires have good thinking skills, and asking questions is a good way to show that you can think on your feet. Another aspect of asking questions is to research the company so you can ask intelligent questions while showing that you have done your research. If you don't have any questions at all, it could seem like you don't care enough about getting the job to think and prepare.
7. Lying about qualifications (or anything else)
Most interview lies are caught eventually, so it's better to be truthful even if it costs you the job. Your qualifications, salary, and other details can be verified easily. Besides, if you lie about what you can do, your job performance will show the truth. If you can't handle the job, you will be let go at some point anyway.
