Everybody else does. Not doing so just puts you behind the rest of the pack. Work out what your own personal line-in-the-sand between "exaggeration" and "outright lying" is, work out what you can plausibly exaggerate - and whether your references will support those exaggerations. You (probably) need to make at least _some_ of your Github or side project work sound on your resume like "commercial experience", and ideally have someone as a reference for that bit of work who'll back that claim up.

Everybody exaggerates on their resume - the line between that and lying is up to you and your own personal ethics.

You 100% wouldn't be the first person to land your job (first or not) based on a lie. Make sure you can back the lie up though, and try to make it a small enough lie that the next resume doesn't need to perpetuate it (you don't want to be the CTO trying to explain away why the company about us page lists you as graduating from Harvard...).
