How you choose to dress for an interview lets others know that you take the interview process seriously and that you pay attention to detail. Here are some recommendations based on my personal experience, for attending a job interview.
Generally, you should always attend an interview in Business Professional attire unless specifically asked to dress in Business Casual. Business casual is more appropriate on a daily basis at your job, if allowed.
I recommend wearing a tailored suit (skirt or pants) or a sheath dress in a neutral shade (black, navy blue, grey), minimal makeup (tutorial coming soon), minimal jewelry (wedding ring if any, simple stud earrings, simple watch). You can use either a basic black handbag with your phone (turned off during the interview), breath mints, a pen & notepad, business card (if applicable), identification card (Driver's License or ID) and copies of your resume, cover letter and the job description.
I would recommend a pair of black or nude whole shoes (no peep toes, sling back etc) in kitten heels or flats.
Also, stick to a bun or slicked back ponytail as it is deemed more professional and is less distracting.
Ensure that your fingernails are well manicured, trimmed and filed. Stick to either natural nails with a clear polish or a neutral color such as nude or a french manicure.
The night before your interview prepare your outfit by ironing or steaming it to ensure that it is wrinkle free, ensure that your shoes are clean and scoff free, and try on the outfit to ensure that it fits appropriately (not too fitted, short or baggy).
If you have a tattoo, ensure that it is being covered up by your outfit otherwise cover it up with heavy coverage foundation as it can be a bit off putting to the interviewer.
Preparation is key. Ensure that you've done research on the company and the position, I would recommended referring to Glassdoor where you can find information about the company's culture with reviews from current or past employees, interview process by those who have been through it and salary information.
Prepare responses for the questions you know they will ask: behavioral questions such as "Tell us a time you.." or specifics about your previous roles. The Muse is helpful online tool where you can get advice on how to respond to interview questions and other career advice.
Plan ahead. Give yourself ample time to arrive at the job interview location with at least 15 minutes contingency. If the interview is at 3:30 PM, I head to the location for 3:00 PM and I wait in the parking lot while reviewing my notes. I head into the office 15 minutes before the interview which shows that you respect their time and you are prompt.
Memorize the name of the person you are supposed to meet with so that you can greet them. Your mobile phone should be turned off completely before entering the office and also take this time to use the rest room before your interview begins.
If they ask if you would like a glass or bottle of water, politely say yes. Sometimes you become nervous and you are going to be speaking for approximately 30-60 mins so it may come in handy.
Even more important in the interview, is the non verbal cues. You can recite the best response to an interview question but if you do so while staring down at your shoes and don't make eye contact. Eye contact is key, it shows confidence.
I also encourage you to smile politely throughout the interview, keep your legs crossed at the ankles (especially when wearing a skirt suit) and also have your hands clasped together in front of you instead of having them crossed or dangling at your sides. Do not chew gum, if you prefer you can have a small mint before the interview just to ensure fresh breath.
After you've completed the interview, don't forget about the follow up process. Following up in a timely manner shows your continued interest, might set you apart from other candidates and also provide a gentle reminder to the recruiter. I suggest a follow up email within 2 days of the interview reinforcing your interest in the position.
I hope that these tips will be helpful to all of you in the job seeking phase and that it will help you land your dream job. The most important rule is to exude confidence, tell yourself you will land this job and that you are the best candidate.
