Morgan Stanley C++ Software Developer interview questions

Early this year I had an introductory phone interview with a person at MS. They told me to wait a few days for the next interview. Weeks had gone by with no response. A few months later I get contacted by another person at MS for the same introductory interview. I ask them why I hadn't heard back from the original person and they said it must've been because the position had gotten filled. Okay, no problem. But the least they could've done is let me know. I finish the introductory interview and then 2 weeks later I have my first technical interview. One of the guys who conducted the interview said he'll recommend that I get passed along to the next stage. A week goes by and I ask for an update from the recruiter about whether I'm being passed to the next stage. She says no update. 2 weeks goes by and I ask again. No update. 3 weeks, no update. It's been 4 MONTHS and I have not heard back from Morgan Stanley and when I ask my original recruiter, she doesn't say that I've been rejected. She simply says there's been no update to my application status. I expected far more professionalism from this company. This is one of the worst interviews I've ever done. I would not recommend applying.

the first interview was technical. the question was about the string to integer function. I had to implement a function to convert the string to an integer. I answer to the question and after 3 days they send me an email for the second interview.
