  1. Post about programming, interesting repos, learning to program, etc. Let's try to keep free software posts in the c/libre comm unless the post is about the programming/is to the repo.

  2. Do not doxx yourself by posting a repo that is yours and in any way leads to your personally identifying information. Use reports if necessary to alert mods to a potential doxxing.

  3. Be kind, keep struggle sessions focused on the topic of programming.

Coding Challenges to Practice (hexbear.net)

So I have an interview coming up sometime in the next 2 weeks and I have to do a few coding and SQL problems as part of it. I wanna start practicing now because I've gotten a bit rusty on algs and such. Does anyone have any suggestions on like array sorts and such to work on or like code golf sites to use? I have Leetcode pulled up and will be working a bit through that today but I just wanna get in as much practice as I can leading up to the interview. I donno when the interview will be but I just heard through the grapevine that there will be one.

I've been working on my own webdev stuff but the most I've had to touch JavaScript for is basically conditionals and loops, so I feel like I've fallen down on the other stuff a bit.

TIA

Also, to add to this, in my experience it helps to have a few algorithms memorized. I learned Red Black Trees, Bubble Sort, Merge Sort (and why it's always faster than Bubble Sort), and how to write a stack. There are undoubtedly other ones to memorize, too, but these came up a lot in my interviews. They usually will not say, "hey, write a bubble sort real quick", but if you can hammer it out when they ask you to find the smallest item in an array or whatever, they'll be pleased. And when they ask how you could speed it up, swap out bubble sort for merge sort. It's just good info to have in your tool box.
