Not the op but, I've seen this for lots of reasons.

Sometimes just a roll of the dice. Large companies tend to lay off more. If you've only worked in startups, it's very possible you may never be laid off. I've never been laid off despite working 20 years in industry.

Working in banks, FAGMAN, etc, you are much more likely to be laid off. I guess you could consider that high-risk, but those jobs are low-risk overall imo, because they pay a lot more than startups.
