Genomic Life interview questions

Submitted app online (day 0). Met with HR rep day 1 to go over standard HR questions and some baseline data questions (have you worked with x tool before?), very nice, she spoke to me as if I had the job in hand. Told me it was a 4 interview process (including this one). Then met with the person overseeing the DS in second interview (day 2). She was also very kind and nice, asked very general questions. It seemed more to be getting a feel for culture fit. Then met with the data team managers following week. Started distanced in tone and manner and then they softened as I spoke with them, was even able to share some laughs. They asked more broad picture questions, very conversational, just getting a general feel for my experience with the various tools. Nothing in depth to prove specific knowledge. Then I didn't hear from the company for a week, contacted HR, she said they were still interviewing other candidates and would have an answer the next week. Next week came and went. Then the following week, got the 'deferred' email. Ultimately they were looking for a data engineer rather than a true data scientist, which i did not fit the bill of.
