Each service has its pros and cons:
The Leetcode is slow, has a high entry threshold, without experience it is very difficult to understand.
Algoexpert works at lightning speed, contains instructions for beginners and questions selected by importance. Updates appear more often than I can track them. I never wanted to return money.
I purchased and went through MLExpert and it was not helpful at all. The crash course didn't explain the core concepts in detail and was too fast paced without providing any good relevant examples. There weren't many practice problems to begin with and the problems didn't really provide good applicable practice. Overall, I don't feel like I got anything out of the service and would go as far as to say it was absolutely useless. Really just payed hundred dollars for nothing.
I am really sorry to say but you are providing the worst services to the customers. I bought the course on 30th July and really didn't like the interface of your website. I requested for the refund on the same day of buying i. E. 30th July. I didn't know that your terms and conditions are terrible as hell and you don't do any refunds. If that's the case, then I have to make others aware that you are the worst company that does not even refund the money to the customers on the same day of buying if they are not satisfied with the product. Really disappointed with your service. Worst company ever!
Their interview questions are pretty basic and the whole product is pretty much useless. Waste of time and money.
