Don'ts

Don’t: offer unnecessary details. The interviewer wants to get to know you, but sharing long stories or irrelevant information can distract from your qualifications. Offer concise answers that relate to the role and company.
Don’t: ramble. Preparing ahead of time what details to include in your answers should help you avoid extra language and info that could occur when you’re nervous.
Don’t: forget to listen and stay focused on the information your interviewer is providing you, and use this information to answer their questions more specifically.
Don’t: interrupt your interviewer when you have a question or need clarification but do wait for a pause in the conversation to ask short questions. Asking questions specific to what they are saying or asking of you is important to show that you understand and are engaged in the conversation.
Don’t: wear bold clothing or strong perfume, as they can be distracting.
Don’t: fidget or make nervous movements with your hands.
Don’t: dress down or casually in an effort to fit with the culture. It’s always better to dress more professionally than not professionally enough.
Don’t: cross your arms or use body language that could make you seem closed off.
Don’t: wait until the morning of an interview to gather your materials. Unexpected difficulties could easily make you late for your interview, which could impact the hiring manager’s first impression of you.
Don’t: be late. You should plan enough time to arrive at the interview location at least 10 minutes early.
Don’t: try to memorize your answers to interview questions. Instead, remember the key points you want to convey
