I worked at Goldman Sachs full-time (More than 10 years)
They take care of their people in every way. Very impressive facility at the NYC headquarters, with all the comforts. Strong corporate structure to make sure no one is misused. Good, transparent leadership.
Not really a con, but not a lot of handholding if you are a slow learner. They expect top-tier, smart work from every employee. If you want to move up from an administrative position, you will have to lobby for it - nothing will just fall in your lap here.
I applied online. The process took 4 weeks. I interviewed at Goldman Sachs.
First it comes a telephone interview which includes very typical questions like why would you apply for Goldman, who you are and what do you expect from working at here, etc...
After a couple of weeks, I got the face to face interview opportunity.
The technical questions are about finance,numbers, Excel and VBA. I had a couple tough ones but managed to solve some. Do prepare for the work experience listed in your CV.
