Wipro Interview Experience

I really need some insights here, please read it and help me out. I had an interview at Wipro for Angular and NodeJS. It was L1 technical round. 1st question was on authentication which went well, the interviewer was satisfied. 2nd question was to find the most occurred element in an array which I did. 3rd question was to write 2 promises and tell a solution to get the result after both of them completes I told about allSetteled api on promise. But my mistake was with syntax. We have to pass promises in an array in allSetteled, but I forgot to pass them in array and got error.

The interviewer just stopped the interview there, wasn't happy.

Was it really bad? At least I knew the correct api to use. Should has he given another chance??
