Moderate questions in written and interview. 2 out of 3 questions are required to solve. Interview has 3 phase followed by HR round. DSA algorithm is must to crack the interview. Hacker rank hacker earth may be a good place to prepare yourself

I got call for interview on immediate basis. Interviewer has his camera off which was already not comfortable to me. He jumped to coding part directly JAVA and SQL. I solved those after that he gave me one Table in 'NOTEPAD' in which rows where stored into string format. He asked me to automate that without telling which language he is expecting or framework. I tried to ask him to elaborate question more but he said very rudely that i have given you a table now automate that! I tried my best to answer but as I couldn't see his facial expressions for further 56 minutes interview I could not get that he was really satisfied with my answers or not. Worst interview ever!
