If and when you land an OMM gig or join a new trading desk you should take a look at the fully automated curve fitting algo that my group and 20+ other OMM desks are currently utilizing to set their Trade Sheets. Here is a snapshot of what it looks like:

You can tailor each IV curve's level of smoothness, variability, and evolution based on your product, market conditions, and personal preference. We currently have an S&P 500 group that uses the algo to update and generate 40+ curves as frequently as every second for all SPX, SPY, e-minis, and VIX futures option expirations. This includes all actively quoted serial, quarterly, and weekly contracts which they trade and monitor. If you're still managing and maintaining your IV curves manually by hand, you're operating at a significant disadvantage to groups using our curve fitter.
