Pros
I honestly can't think of any positive reason why you would want to work at Bark unless you class getting drunk as a 'pro'.
Cons
I honestly now wonder why I took the job. I was in between jobs and the pay really wasn't that great but I thought at first it looked a decent place to work. Oh how wrong could I be? If you want to see how morally corrupt the CEO of Bark is then just Google 'Bark.com spam'. Read through the search results and ask yourself do you really want to be involved in this? The CEO isnt very smart so you will tend to find everything is done at a very low level. If you are a dev get ready for architecture from the 1990s. Don't try to explain anything to him or even try to suggest doing something properly he won't listen and will smash on making a mess of everything. Worst part is that the CEO actually think what they are doing is ground breaking. Oh yeah and the 'shares' you get in Bark.com are pretty worthless.
