You get to be part of a historic change in the way people work. Whether that change is for the good will be up to history.

Some of the engineering challenges are interesting and hard and are being tackled by few others. (Lots of other challenges are being tackled by lots of competitors, and I don't know whether they would be better to work for.)

Guided by a strong mission and set of core values. If you believe in them, you will fit in well and they can keep you going through the long hours.

• Apparently, a lack of transparency. I was oblivious to all of the scandals that have been in the news lately, which disturbs me.

• If you don't believe in all the values, you won't fit in. The values are basically not available publicly, and I don't know if they are shared with candidates during recruiting, so make sure you find out what they are.

• It seems like the IPO may be more elusive than at other startups. One starts to wonder if they are putting it off to squeeze more work out of the employees.

• I don't know how common this is, but I was terminated, to the great sadness and detriment of my team, by a higher-level manager for what seemed like an irrelevant issue.

• Remote work is severely discouraged.

Be honest and forthcoming. In this day and age, the truth will out sooner than later anyway.
