Responsible for 

Words like this, as well as "oversight of," and "duties included," are unnecessarily complicated. Aim to always be straightforward, concise, and use active verbs to describe your abilities and accomplishments. Instead of putting, "Responsible for mentoring interns" simply write, "Mentored interns" 

Writing this word on your resume makes it seem like you were put in a situation that you did not exactly want to fulfill and just want to get it over with. So, it would be best if you do not put this is your resume. It does not sound appealing and is definitely a weak term to express what tasks you were "responsible for". You may replace this word with phrases like “managed,” “led,” “supervised,” etc. These words make it sound more spot on and professional.

Skillful 

This has got to be one of the most used words that you will ever see in generic resumes. Putting the word “skillful” inside your resume is quite redundant because a resume is literally a big list of all your skill sets.  

Overusing this word would be such a drag to recruiters and potential employers to read. Thus, keeping it simple and highlighting only the skills that are relevant to which position you are applying for is a way to go.  

Hard-working  

Don’t get us wrong, there is nothing wrong with being hard-working. Recruiters do look out for hard workers. However, proving that you are a hard worker is so much more than putting in on your resume. You must perform and stand by it. It is much more important that you can show and not just tell. 

Most industries look at creativity, focus, or expertise as more valuable. You do not even need to be a hard worker to get the job done. Try finding terms that would still imply that you are indeed a hard worker but in a way that counts because anyone can label themselves as a hard worker. Your resume will be a lot more convincing if you were to list out concrete details on what hard work you have done. 

Assisted 

The word “assisted” will seem like you are downplaying your contribution to corporate projects. Always keep in mind that, in creating your resume, you must aim to stand out among the rest and take pride in what accomplishments that you have made. Saying that you only “assisted” in doing something in a project might imply that you just stood there while others were doing all the important work. It would be better to say that you have “contributed to,” “facilitated in,” or “collaborated with” instead.  

Ambitious 

While you obviously want to display some level of ambition in the hiring process, putting focus on the word “ambitious” can be a deal-breaker to some. It may imply that you are just settling for the given position at the moment but then be quickly dissatisfied and want more in the long run, rather than aiming to excel and gain expertise in the position you were given.  

Slang or casual texting words 

Avoid using internet slang or casual texting language in your resume at all costs. It would be passable if you were to create a resume for a creatives position or enter the advertising industry. However, a resume must be formal and professional because this is the first impression a recruiter or potential employer has of you. Do not use words such as lit, cool, highkey or lowkey, etc. As much as it brings character to the resume, there is just a time and a place for all that quirkiness. Your professionalism should reflect on your resume.  

Personal pronouns 

Your resume should always be written in first person, but you do not necessarily need to put in “I.” In some cases, other people would repeatedly put “I” in every sentence in their resume. For example, instead of writing “I proposed and implemented a new process,” just write “Proposed and implemented a new process.” As much as possible, avoid constantly using personal pronouns like I, me, my, we, or our.
