IMHO fun educational learning languages aren't general purpose or production ready; and so also at this point in my career I would appreciate a more reusable language in a CS curriculum.

I'm not sure why you assume it has to be hundreds of hours. Take a look at something like https://github.com/jwasham/coding-interview-university, which has a lot of different topics. In interview loops I've done recently, I realized I was most nervous around Systems/Scaling and Graph (e.g. Dijkstra's) questions, so took some time to work on those. You don't have to do like the author of that piece and work for hundreds of hours. If trees are proving a problem or are an area you know you aren't so up on, then use studying to fill in the gap. Anything is better than nothing, and studying for, let's say, 10 hours might make you just more comfortable with the topic to turn the interview in a more positive direction.

In Poll: Is the leetcode grind necessary to land a high paying remote job?
I got this push message from Hacker News this morning and felt obliged to post my opinion on the "LeetCode thing" cause I'm currently trying the same thing as you are. I have a master degree on CS and 4 years of professional experience and trying to keep moving forward. I don't believe solving LeetCode problems well is something that you have to be gifted to achieve. Ironically, I believed it once upon a time. I got very frustrated when failed tech interviews for Microsoft and Google when I was a new-grad and trying to find a decent job. I know it's frustrating to just look at somebody finishing all the contest problems in 10min and you're scratching your head for many hours or even a whole day. Believe me I was literaly doing this for a long time. But I started my professional occupation anyway. What I did then is keep trying for several

years since I know I'm stupid and stubborn. It turns out to be promising in the third year doing so. I gradually find out there IS a way! There is a clear and straightforward path to do better in algorithm problems: just get a full list of basic data structures and algorithms, understand them all by watching youtube videos, learning online courses (MIT online courses helped be a lot), and practice tens of problems in each subject until you get sick of it. Currently I get 2481 points in LeetCode contest and I'm preparing for my next period of career and hope these hard work finally pay off! In case someone need it, these 2 lists are very comprehensive and helped me a lot: * https://github.com/jwasham/coding-interview-university * https://techdevguide.withgoogle.com/ Hope it helps!

Ask HN: Switch from Technology Analyst to Software Engineering

I have an undergraduate degree in computer science but I have never had a software engineering job. I worked for a year as a BA and then went ahead and did my master's in information systems. I have now been working as a Technology Analyst at a decent sized firm where I basically do all BA stuff, document requirements, JIRA, Scrum etc. I'm now realizing that BA/Project Manager work might not be the best fit for me. I do not enjoy my work and it gets pretty mundane. Is it too late to get back into software engineering? I have had a couple of internships where I wrote some code (not pure development internships) but I have never really worked in a professional software development environment. I also have some personal projects that I can put on my resume. To upsert my knowledge of computer science, I have started working through this (on t

he graphs section right now): https://github.com/jwasham/coding-interview-university. I also try to do leetcode problems on the topics I cover. I plan to follow this guide for the most part. Do you see any gaping holes in my intent/plan to get into software engineering? Do you think it is doable? If it is doable, do you have any recommendations in terms of the process that I should follow? Really appreciate any advice or feedback.
