How a Recent Grad Built a 660+ Day Streak on CodeSignal Learn
How do you stay consistent for 660+ days straight? We asked Esther Ogundele, a Computer Science and Spanish grad from Fisk University who has learned on CodeSignal Learn every single day for nearly two years. In this conversation, Esther shares how a Google Tech Exchange program first introduced her to CodeSignal Learn, why the streak feature keeps her motivated instead of stressed, and how she's building a well-rounded skill set, from front-end engineering to project management to public speaking, for a world where technical fluency matters in every role. Whether you're job hunting, prepping for grad school, or just trying to build a daily learning habit that sticks, Esther's story is full of practical takeaways. What she covers: • How she first discovered CodeSignal Learn through Google Tech Exchange • What she's learning now and how it connects to her goals • Why a single daily exercise is enough to keep the momentum going • The "Tomorrow Starts Tonight" habit that makes time for learning • What it's like learning with Cosmo, your AI tutor • Her advice for anyone who wants to start but isn't sure where to begin Esther's biggest tip? Start small. "It doesn't hurt to just start. Giving it that first push goes a long way." — Ready to build the skills you need for your next role or your next chapter?
