Morgan Stanley Software Engineer(Internship) interview questions

After applying and going through the behavioral questionnaire, i waited for 3 months to get feedback from them. After multiple send emails and calls ( trying to find out if the interview process is still going) I was invited for an interview which was rescheduled a few days later. The day before the rescheduled interview I got a call saying that they will not be going forward as they have already filled the position. Overall Extremely disappointed with the company and their lack of communication skills.
