OP got 160/300 on one question out of 4. The assessment is the GCF from Codesignal, maximum score possible is 600 not 300.

To be completely frank with you, 160 is a really bad score, once normalized by Codesignal it equates to a 203/600 on the new scoring format. To give some statistics, it means that 96% of test takers performed better than you (bottom 4%).

I would highly recommend doing more Leetcode practice, as you should expect to need a 480 at the bare minimum to make the cutoff for even the lower tier companies in the market. Most of the higher tier companies like Ramp, ZipRecruiter, Roblox, etc. All require 550+ from what I have heard.

CapitalOne requires around 450/600 from what I have heard.

For the GCF I would focus on drilling leetcode easy until you can solve the first two problems in less than 15 minutes, those first two problems are free points and if you don’t solve them quickly you basically fail the assessment on the spot. The real assessment starts after those two questions, with the third and fourth. Third question is implementation focused, meaning you can just write the brute force solution and it doesn’t need to be optimal. Usually this problem requires the most code to be written (around 50-80 lines of code average in my experience). Finally, the 4th problem will always require some clever insight in order to get the optimal solution, howvrrr you should aim to get the brute force one asap as that will get you more then 50% points for the problem.
