<p>This is at a local company btw. Should I wear a button down with tie? suit? thanks.</p>
<p>Yes. Suit and tie or blazer, tie, slacks at minimum. </p>
<p>So I can’t just wear a blue button down with tie and slacks? Is a suit/blazer truly necessary?</p>
<p>bump</p>
<p>It depends on the company, although less dressy companies are more tolerant of overdressiness than vice-versa.</p>
<p>If you know someone who works at the company, you may want to ask that person how dressy the company is.</p>
<p>Assume any interview, at any level, is suit and tie. The only exception is if the person setting up the interview explicitly gives a dress code.</p>
<p>A general rule of thumb is to dress one step more formally than you would on the job, if possible. So if you would dress business casual (nice shirt and slacks) during the job, dress business (suit) during the interview. If your going to wear jeans and a t-shirt during the internship, a nice dress shirt and slacks during the interview should be fine.</p>
<p>If you’re ever in doubt though, it’s always better to be overdressed than underdressed.</p>
<p>Of course, make sure the dressy clothes fit properly. Dressy clothes are meant to look good, but poorly fitting dressy clothes look bad. Do not wait until the morning of interview day to find out that the clothes do not fit because you have not worn them since high school.</p>
