Resume without a skills section

I don't think it's a dealbreaker by any means. You can talk about it verbally, but not sure how strong your resume is to get the interview. You can read stories on here about people putting Excel on their resume as a skill and then getting grilled in an ib interview.

If you put MS Office on your resume it will go straight to the bin. While you probably already know this, I do want this information to get to anyone who might read this and did not know. MS Office is considered a standard. It is more likely that being unskilled in MSO will be highlighted compared to being skilled. That being said, if you have great skills in excel, this could be highlighted. You can take courses such as the street of walls that will teach you the skills needed for financial modeling, statements and other skills within excel needed for IB/PE/HF. You can also get free learning on Capiq, salesforce, as well as paid learning for Bloomberg, etc. Lynda is a great resource as well that will link to LinkedIn.

I would recommend downloading some financial statements for random companies on yahoo finance and try modeling them into excel, and try to complete them without using a mouse.

You should include a skills section that lists computer-related skills (e.g. MS Office, CapIQ, Bloomberg), any languages you speak, any certifications you have, and an interests line. There is no way you have too much experience to where you cannot fit this section in,

Unless the skill makes you different, don't bother. Free up more space for experiences.
