There are few interview experiences shared here in Glassdoor mentioning that CashKaro is a scam. I vouch for it. They're a clever con artists. They ask you to do sample project then there is no show. For me they asked to write test automation script for 4 of their major workflows. I spent 3 days, worked till 4 AM to complete the assignment. They didn't bother to respond back. My advise to all future interview candidates, please be wary of them.
