Nasdaq interview questions

I applied online and within a few days I received an email from a recruitrer in PA, (the job was in NY) requesting a phone interview with me and requested my availability for the next week. When I replied back a couple of hours later, no response back. I followed up a few days later, never heard back.

- Initial brief phone call with recruiter. Typical conversation about background. - 45 minute conversation with manager going over technical background. Pleasant conversation about goals/future expectations. Seemed liked a really nice guy. Sent a take home assignment for me to do in a short amount of time. Requirements were open ended but somewhat confusing, so I had to clarify with follow up email. - Several days later I had a 30 minute phone call with a senior/lead architect who was really nice. Went over background and asked some technical questions around technology and API design. Nothing complicated at all. - Final interview was supposed to be with 5 people. For me it was only two, with the third being sick. First part was with the manager from the phone who just asked a white board design question about building and scaling out an app, and then a brain teaser. No chit chat like on the phone, just straight to technical. Second part was with a developer who went over Java technical questions about threads, Spring framework, hashmaps, OOP, etc. Third guy was out sick but manager said he would contact me about scheduling a video chat later in the week. I reached out to manager the next day but never heard back. Got an automated email a couple days later from Nasdaq saying they went with someone else. Besides the take home project, the interview process was pretty straight forward. The people I spoke or met with all seemed to be really nice people to work with. All the technologies and projects discussed seemed really interesting. Not sure what happened at the end of the interview process. Would have been better if manager just said recruiter would reach out to me instead of leading me to believe there would be another interview. Either way I enjoyed the interview and thought it was a great opportunity.
