ZipGo ETL/Tableau Developer interview questions

The process took 3 days. I applied through AngelList and got a call after a week. First round was telephonic round, which was kind of basic screening. I got a call next day that your first round is done we want you to meet in person. I accepted the invitation and went to ZipGo office Koramangla. First round started it went 1.25 hour long, it was a very nice interview. Interviewer was very professional. He asked questions related to ETL mapping, data transformation, Complex SQL queries and Puzzles. I replied to all the questions except one puzzle. This rounf was done and he informed me that I need to wait for next round. Next round was with CTO of ZipGo, the most unprofessional CTO I have ever met. He came and started with a very arrogant way. He clearly said that for him ETL means nothing it is just drag and drop so let's discuss something else (which was not at all mentioned in JD). He started asking irrelevant question, which was not at all related to the profile. Previous interviewer with whom I was supposed to work (if selected), was fine with my skills and told me that there are only few things; you will learn easily and it will be nice to work with you, your skills are good. But Mr. CTO was expecting everything form me, Business Analytics, Data Analytics, Business Intelligence & ETL and Some part of Data Science; I was so confused that these people have not coordinated with each other. One is saying my skill is fine for this position another one is expecting 6 roles in this one role. So better they should have given in the JD. My suggestion is please go through the JD carefully before attending the interview. And one suggestion for Mr. CTo, if you will read this - 1) please coordinate with your team and share the expected JD. (2) You should know how to talk with a candidate, it's not a fish market. It is an interview
