Citi Application Support Analyst interview questions

I had an interview scheduled with two people, but the panel actually included five. They asked many challenging questions, and I did my best to answer them. A week later, the recruiter called to say I was being offered the job and began the process for the offer letter. I was asked to upload my photo and complete some questionnaires. After the long weekend, the same recruiter called and said they had decided to move forward with another candidate. It’s disappointing to receive an offer and then have it withdrawn. I wish the decision-making process had been more thorough.
