Janssen Business Development Manager interview questions

Multiple (4+) interview rounds over about 2 months, with different stakeholders (7+ people) in the company. Extensive preparation and follow-up time invested by the candidate. No case study nor assessment center. Not having experience in the sector was only (!) reason for rejection provided by Janssen - isn´t that visible in the CV right away? Either the given explanation is an excuse, or Janssen simply wasted a significant amount of my time. No comment nor apology was given my Janssen for this recruitment process. In any case, disrespectful and unprofessional behaviour. Very disappointing!
