Level of Knowledge Needed

[bobthebuilder]

I'm an undergrad going for summer 20 quant internships. Most interview questions I've found seem to be brain-teasers based on intro stats/combinatorics. My question is how much beyond the basics do I need to know? For example will I be expected to know about martingales? In other words, is it better to just focus on doing practice problems or do I need to learn more about probability/optimization/etc? I'm considering firms like Jane Street & Two Sigma if that makes a difference, although certainly am not hard set. I'm a math/cs double major if that matters.

Also, I spent the past 2 summers at FAANG. Is that enough to get an interview? If not what do kinds of things do people do to improve their resume.

And is it true that most places are willing to teach you the finance once you start? Right now I know nothing about finance.

Thanks in advance.

You just need to know the basics and be smart enough to answer brain teasers and pass HackerRank coding challenges. FAANG is absolutely enough, you'll get called in if you have them on your resume. They'll teach you everything you need to know. You're in a great place man, I wouldn't worry about it.

Maybe look at heard on the street, common quantitative interview questions. There’s also 150 most common quantitative interview questions by Stefanica and Radowic (sp?). And the green book - the title of which I can’t remember offf hand. They love that stuff.
