First, you go with a consulting company. After they "hire" you, they send your profile to Morgan Stanley. Morgan Stanley then sends you a Zoom invite.

The consulting company tries to give you hints about the interview questions, but it's totally the opposite of what they will ask.

Morgan Stanley's team will interview you via Zoom but will be busy, so you end up with one engineer. There's no webcam, only screen sharing.

The consulting company will tell you the questions are theoretical. Well, no, you must have an IDE and a Java compiler ready. Otherwise, you'll miss the interview, even if no one told you to prepare your computer.

Also, an important point: The consulting company will tell you the interview is in French (as you are a French speaker), but it's not at all. No one speaks French, so you must deal with English.

One important note: Morgan Stanley staff is VERY kind and friendly. I was so stressed because I wasn't ready for live coding and having to speak English, but the person tried to reassure me, even though I was overstressed.

I wish the consulting company had told me accurate information.
