When they reached out to me two years ago and assigned tasks, I explicitly told them that I would not complete assignments because, based on my prior experience, it wasn't worth the effort. I mentioned that companies often do not provide feedback even after investing a significant amount of time. At that time, they tried to convince me to complete the assignments, but I declined.
Now, after two years, they have contacted me again. I accepted the assignment, which involved developing a wallet app, designing both the frontend and backend, and deploying it on servers. I successfully completed all the tasks and submitted my assignment. However, it seems they now lack the time to provide feedback. If you are already in a good position, I would advise against investing your precious time in their interviews. It appears to be a one-way communication situation, where they may not even take the time to understand the work you have done. If you are in need, then you can consider pursuing opportunities with them.
