Yzzxy that is litterally and exactly what the group is about.
While there are some shortcuts they largely rely on having seen a problem before.
Many top tier interviewers can ask you problems you can't have seen before and then all you will have left is your though process.
The group is about exposing yourself to lots of problems to pick up tricks and shortcuts but also to learn about the underlying theories and thought processes that created them as well and sharing that knowledge with others on the journey as well.
> While there are some shortcuts they largely rely on having seen a problem before.
I'm arguing that this is largely not true. These problems are grounded in basic CS[0] problems - implementing stacks, linked lists, standard sorts, or understanding how to solve a basic problem in a certain O time. They are not "interview problems" that recruiters invent and pass around to one anther, they are real problems with historical backgrounds and well-discussed solutions.
I'm not saying your group shouldn't exist, I'm saying I disagree with your stated method:
> expose yourself to enough problems and solutions
Instead, expose yourself to computer science. Few interview questions (for entry-midlevel coding jobs) are novel, almost all of them (that I've seen) are just exemplifications of well-known CS problems[1] that you will encounter in an intro algorithms textbook. The others tend to be domain specific and can't really be studied for anyway (write a basic X in framework Y).
There's no reason to frame this learning as interview training beyond when you state the benefits of it for marketing[2]. There's no magical distinction between programming and interviewing, there are just some abstract topics that happen to be tested by interviewers and are also used in real life.
[0] Not programming, computer science
[1] When I say problem here it means something slightly different than a test question. The definition is closer to "a research question that was once, and may still be, unsolved."
[2] Don't take this as an implication that you should be running a business, marketing is just part of making a good thing. It's understanding your users.
