Xylem Senior Technical Writer interview questions

Absolutely pathetic. I have over 7 years of experience in technical writing but I was made to write an online assessment comprising elementary questions on English grammar. I attended hoping that would be just a way to filter out applicants. Turns out I was wrong. Though I got selected, the HR went on to schedule 4+ rounds after this round and even at the end of 5 rounds, they never gave clarity on when we would get to discuss the terms of the offer. I was extremely patient from the beginning but I lost it when both HR and hiring manager asked about my family details (they wanted to know everything including my relationship details), and were very keen on why I live in a particular part of the city. I mean you're hiring for a tech writer, not a goddamn CEO! 5+ rounds and no idea whether you like a candidate or not! You gotta be f*cking kidding me.
