As somebody who has been interviewing recently, the format I've preferred is from TestDome. I've never used leetcode or others but I imagine they're similar. I had 4 coding problems for which I had to pass a set of test cases which were explained from a high level. The first 3 were fairly easy and had time limits of 10 minutes or so. The last one was more involved from a design and functionality perspective and had a limit of 45 minutes. Then, it was followed up by a conversation with a developer where we discussed the problems and approaches. The time commitment was finite and reasonable, and the opportunity to explain my code was appreciated.
