I have been working at Goldman Sachs full-time (More than 10 years)
Great culture, great people, nimble and forward looking
At times can be a but bearacratic
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.
