One of the worst interview experience with CoinDCX

So I applied on Coindcx website for an open role about a week ago. Their HR “manager” called me after CV review and asked general questions like past role, why looking for a change etc. Then came the CTC part. He said my expected CTC is out of their budget as their budget is like 10% increment from my current role but he will try to stretch to 15%, the next day I called and said since I need to move city as well if you can get upto 20, I am good. His response “lets start the process and then we will see” Next day Round 1. The person join the called and was without camera, even though my camera was on (I always thought its common courtesy to have camera on). From her way of talking it looked she was not prepared or afraid to take interview. There was no introduction, no hello, we straight away went to interview. She said she will ask 1 DSA question, 1 SQL question then some theory. I solved the DSA question, she asked me to add few things I did, now her reaction to this was (I am not able to understand how your code works so I am not sure it will give output). Then we went to SQL question, her question had incorrect values and I had to point it out to her, I solved that as well with some assumptions as I forgot some syntax. She then forgot the actual output and said your output is incorrect then I showed this is what you asked so she was like okay Then abruptly we ended the interview when she said please ask any questions which I asked around work, even that she was not answering correctly. It was like either she was not interested or she was afraid. Within hours I got rejection mail as well. So either because of CTC they did a formal interview (which I am like you can say you are out of budget), or if your interviewer is not good please get it fixed. Will never apply for this company for sure
