Shopflo interview questions

I got the interview through a referral. The interviewer did not make me feel comfortable at all. He asked me to write polyfills (JS). I wrote the first one and then I got a little stuck in the second one. They were random functions from Loadash. We were having a bug in second one which wasn't related to my function at all, there were 3 parts and i was done with first one. It took us 20 mins to debug and when it worked I asked him out of curiosity why and he was like he is not sure. I thought okay that's fine. We were times up and I knew that I will not make it to the next round, which is also fine. But later on I got to know that he told HR that I couldn't solve anything. I didnt solve even one question. WHICH IS A LIE. Later on i ot to know he has done the same with another candidate who was referred by someone else. Not sure why he wouldnt pass anyone or what are their expectation from freshers.
