We’ve designed AlgoCademy with people who don’t have a lot of experience with algorithms and data structures in mind. We want to teach people who are looking for the increased satisfaction and income that a programming job can provide.
Is AlgoCademy right for you? Simply put, we're for you if...
- You’re trying to prepare for coding interviews but don’t know where to start, or how to come up with an efficient study plan
- You’ve spent countless hours trying to solve coding questions online, but you’ve grown frustrated, feeling like you can’t build a solution from scratch
- Even if you are able to devise an approach that solves your coding challenge, you aren’t able to write quality code which passes the coding interview
- You’re looking to gain the speed and accuracy needed to solve a coding challenge that may get asked of you in interviews
- You start to experience sensory overload thinking about all of the information out there about preparing for coding interviews, and you find yourself stuck for days, googling information on various topics, messing up your consistency and flow
