Process
Campus interview first. Asked a lot of questions on machine learning, such as regularization, linear regression, and logistic regression.
Then a coding problem: Two-Sum (given an array and a target sum, find all the pairs that add up to the sum).
Phone interview as the second interview with the hiring manager.
Talked about the team and my skill set. Asked a bunch of questions about machine learning as well; most were concepts and definitions.
Then a coding problem: merge sort.

Pros: 1. Snacks
2. Good employee programs
3. Training (if you are lucky enough to get it)
4. If you are from a certain country, you are in the in-crowd
Cons: 1. Bad managers
2. HR dept
3. Unethical behaviors
4. Bad managers
It seems people who get promoted have NO people skills whatsoever. They are promoted into positions, and then their bad behaviors are covered by higher ups.
A manager can tell you not to rank him/her on the Pulse Surveys negatively.
A manager can tell you there's no room for two seniors on his/her team.
A manager has people skills about the size of a cuticle.
When asked if I could transfer, I was told I could and she/he would make the connections. Well, here I am, unemployed thanks to that manager.
Did you know if you report something that is against company policy, you will be led out the door?
This place favors young people. If you are 40 and above, watch out. They will try somehow, some way to get you out the door.
What kind of HR company does not have an exit interview?
They really don't care what employees (former) think. They only care about the Best Places to Work surveys and will only send them to people who they think will respond favorably to them. They, after all, have a reputation to uphold.
The culture has really gone downhill. It's ruthless and cutthroat, especially in Financials teams.
HR does not care about employees. Only the bottom line. If you report something to HR, be prepared to lose your job.
They tout the whole process of the employee review and being in charge of it now, but it's really not a good process.
If an employee needs to transfer, management should be more supportive, not take it personally and usher that person out the door.
Lots of people protect each other because they all used to work at PSFT together. If you aren't part of that crowd, watch out.
Think twice before accepting a job here, especially in Financials.
