Hi everyone. Hope your breaks are going well. So I applied to a few tech internships over the break and they sent out OAs which are due in like a week or so. I have already done one in the past which was FBU freshman. I have had some coding experience doing many projects and took a cs course so understanding the topic was not bad but actually solving them was an issue and I was only able to solve like 1.5/4 of the problems. I tried another a few days ago which was a practice from CodeSignal and did similarly. I also managed to solve 1 or 2 of the easy problems on Google Kickstart as more practice. Anyone have an tips or suggestions for prepping in the short amount of time I have or tips for doing well on the actual OAs for CodeSignal (and possibly HackerRank)? I really want to do well, but at the same time I'm sort of lost on how to get started or what to focus on and want to take my time to understand the fundamentals clearly.
