Donnelley Financial Solutions (DFIN) Senior Software Engineer In Test interview questions

Total 5 Technical and Behavioral rounds of 30 mins each and it went over for 2 weeks . Asked about my projects and technical stuff I worked on and everything went well..Team was impressed and HR called me after 4- 5 days of interview and said thing are going in right direction and we might make an offer soon.But next day HR calls again and says Senior Leadership has cancelled that role due to operational issues.. It's very bad experience after going through 5 rounds and 2 weeks of time and effort. I hope they don't repeat this with any other candidates .This will go as one of my worst experience
