What people at KeepTruckin say
Reviews originally posted on Glassdoor.
I worked in KT as a software engineer only for around 4 months. . But out of my 7 years as a software engineer it was the best team and best company I had worked for. . I don’t know whether I will get to work for another company like KT or KT itself in future but I really loved most of my time at KT. Unfortunately, I wanted to relocate and also had my life situations/priorities.
The people i worked with were awesome! There was a sense family ties between my teammates.
Applying to KeepTruckin was one of the best things I did for my career. The company open door policy and rapid growth has allowed me to get heard and grow my career at a faster rate. I cannot stress enough the importance of working for a company with good culture. KeepTruckin has it. It just makes coming to work easy.
Demand for the product is rapidly growing. The work is innovative and exciting. New markets are opening up to us. The future of this company looks very bright.
KeepTruckin is one of the few companies I've talked to that is well run from top to bottom. The engineering team is really solid and is run by engineers. Most of the product requests come from customers and are thoroughly thought out before they're implemented.
