I feel somewhat connected to the product in a weird way in that I went through the non profit Codepaths interview prep summer course which is where I heard about Rahul and seems to solve a somewhat similar pain point in that outside of the interview prep piece it allowed me to make connections and receive mentorship from experienced engineers that was incredibly valuable
Another company that I love that scratched that same itch was Hackpack. They charge a monthly membership fee and it's centered around interview prep but the main value I got from being part of the program was deep connections and mentorship with experienced engineers.
I have some small user feedback with a sample size of 1. I love the content that you guys create and consume the majority of the blogs/youtube videos/linkedIn posts but don't use the app much. Content I consume on my phone is almost exclusively hackernews, reddit and youtube. I'm not sure what the blocker is but it is strange to me that given how much I enjoy the content that I don't use the app more.
Congrats on the launch post and wish you both the best!
