It is easy to write on a resume that you are proficient with Excel or other spreadsheeting software. I am sure many people are guilty of putting this on their resume when they, in fact, have little to no familiarity with the software. Do you and your employer a favor by actually learning how to use Excel, at least on a basic level. There are a couple of great online resources you can use to become capable of using Excel with some degree of dexterity. All you need is a weekend to become great at Excel. There are thousands if not millions of tutorial videos on Youtube with the intent to educate people on how to use Excel. Knowing how to use Excel will make you invaluable in an office setting.
For those of you with internships in an office setting, it is important that you figure out what the dress code is. However, I would venture to say that it would be safe to assume that an office probably has a business casual dress code. Of course, there are numerous definitions and trains of thought on what clothing exactly constitutes business casual clothing. Regardless, it would not be a bad idea to purchase or ask a family member to borrow a couple of button up dress shirts and pants. Furthermore it would not be a bad idea to learn how to tie a tie. Again, learning how to tie a basic Windsor knot is only a Youtube video and fifteen minutes of practice away.
This next topic is a little more sensitive than others. Many internships and jobs for that matter have pre-employment drug tests. Failing a pre-employment drug test could lead to an individual losing an internship or job that they worked so hard for. Of constant debate is, of course, the position of the workplace towards cannabis. Even if you are in a recreationally or medical state and you fall within state law in the use of cannabis, you are still violating federal law and therefore a workplace can terminate your employment or internship due to a failed drug test. This is especially true of government offices who do not deviate from Federal law in this regard. Of course certain offices have different approaches to drug tests so it would not be a bad idea to become familiar with the posture of an employer towards this. That being said, if you the aforementioned applies to you, I would recommend halting usage of the offending substance until you are first drug tested or you figure out what the office policy is.
Internships and jobs are important ways to develop oneself professionally and are an important part of building one's resume and experience. Being prepared for your internship will make your summer better and reflect well on you in the eyes of an employer.
