Even as someone who took algo courses in college I still haven't figured out a good way to go about this. In my experience unless I'm doing it every day my fitness will drop off completely in about two weeks.

2-3 problems a day (3-4 hours of study) has been the only approach that's sort of worked for me so far. Best of luck!

You’re about to get destroyed if you haven’t already spent at least 2 months reviewing material and practicing.

Just a fair word of warning. I don’t mean to discourage you, but you can’t expect to waltz in with no practice for these things.

Thanks ....that means that I should walk away .

Nah don't walk away. Do it, and get the experience so you know what to expect next time. You've already scheduled it!

I would hate for my previous comment to have discouraged you from even trying. If it's a simple online coding challenge, it might be pretty straightforward. It's the in-person round of interviews that you really need some solid prep for.

Thanks.... It is online coding challenge.
