What's your top tip for doing well at interview?

My advice for anyone who is going through the interview stage is to do as much preparation as possible. This means researching the company, reviewing the job description, researching the interviewer(s) on LinkedIn, looking at company reviews, reviewing your resume again so that you are prepared to speak to it should you be asked about a project, for example, thinking of questions you want to ask the interviewer(s) - always have a few questions to ask, look up culture, location ahead of time if you are required to meet them in person or go to the office. Another piece of advice is to be yourself, and honest. If you are unsure of a question and don't know how to answer or need the question to be repeated don't hesitate. Remember this is not only the employer interviewing you but you interviewing whether or not the company or the interviewer will be someone you can work with or see yourself with!

My top tip is to be confident and clear in your answers. In addition to what Linda K. mentioned about preparing your questions for the interviewer as well.

Agreed to this statement Mohamed advised. And if you aren't sure of the question or how to answer it, don't be afraid to ask for further clarity regarding it.
