The person behind Routelab

Arjun Mehra, founder of Routelab

Hi, I'm Arjun

Founder · Software Engineer · Creator of Routelab

"I started Routelab in 2021 after failing six coding interviews in a row.

Instead of grinding more problems, I wrote down every pattern I kept missing and shared the notes. Soon people were messaging me about the jobs they landed with them. That kept me going.

A year later, I finally signed an offer myself. Routelab is the path I wish someone had handed me on day one."
