How long did you prep for data science interviews before applying?
Consultant doing technical work, but real work feels more specialized than school. So I've forgotten quite a bit, yet DS interviews at Amazon seem to want us to walk through a wide variety of algorithms.
Should I start studying before I get an interview offer?

Yes. You should always study and brush up on the necessary skills if you’re applying to new jobs. Why would you wait until you get an interview? There’s no such thing as over-preparing, but you can ALWAYS under-prepare

Just got out of one of my final round interviews. It’s been over 8 weeks of prep. Got a little nervous and may have messed up on the case, PEI went okay. Have the other later this week. Trying to focus on that but difficult knowing how this performance would impact the outcome. Has this happened to anyone and they ended up getting offers? Searching for success stories or tips.

I’m in big law and on the cusp of making the jump to in-house. It sounds like the company I just interviewed with is getting ready to make me an offer. It’s definitely going to be a pay cut coming from big law but I do get some nice equity in the company. Is the jump worth it? I’m so burnt out by big law and this seems like an awesome opportunity to help shape a newish company. Any tips on how to figure out if this is the right move for me?

It’s hard to trust the partners/leadership when they want us to return to office as being better when we increase offshoring?

Am I mistaken by this viewpoint?
