Fragen im Vorstellungsgespräch für Beschäftigung als Senior Data Analyst bei Epsilon

Lengthy interview process with frequent changes in interview time slots. I had 3 rounds of interviews over a period of a month and not a single round happened as per the original schedule. All rounds were of average difficulty. Didn’t get the offer but too bad they didnt have the courtesy to atleast respond after I had put in so much of time of effort. Not sure if they had the intention to hire in the first place. Dont recommend.
