Depends what time you work - Uber/Lyft Driver Lyft Employee Review

There are many opportunities to make impact.

This scope does come at the cost of intense working hours

Academic environment that has a lot of interesting science problems from mapping, optimization, plus all the usual user metrics. Rewarding and complex problems that often have a lo t of tradeoff.

For how good the ICs are, leadership is equally bad. Just riddled with poor decisions top/down. Also given the current state, Uber is just too strong of a competitor and you feel that pressure every day.
