You’d be surprised at how many traders and QRs in HFT (or at least in OMM) often reach for Excel. Granted this is way more common among older people in the industry. And as a technologist OP wouldn’t have to worry about writing or maintaining Excel scripts :p

Excel is a very effective tool for many things but suggesting that it would be useful to spend time learning Excel to prepare for HFT is really bad advice.
