Not supposed to disclose. However, I can tell you that, if you have been developing projects of your own and do a deep dive into the concepts you used, you stand a very clear chance to make the cut. For DSA, they don't ask fancy DSA which the company doesn't even use. LL, Queues, Stack, Array and String Manipulation are enough. This is something I admire about whatfix. They only filter out candidates based on their practical knowledge and ability to explore things on their own, which are rarely taught in the academia. Be sure to have badass, multi-disciplinary projects in your arsenal. If you know the projects inside-out, then you would surely enjoy the entire technical interview process.
