Platform9 Systems Front End Lead interview questions

The recruitment team directly contacted me for this position, Name of that lady is "Sandhya Dulgaj". She sent me an assignment for React CRUD operation and some form validation. I did the assignment and completed on time even i have sent 3 different flavours. 1. Native JS + React + Redux 2. ES6 + React + Redux 3. Typescript + React + Redux And after no calls from their end, i did follow up from my end, and answer was constantly same, "They have not given the feedback, we will give feedback with couple of days.", but their couple of days never come. So i set my mind it was fake interview. Requested to Platform9 HR/TA team please don't waste other's time. We know your time is not important but our time is precious.
