McAfee Senior Software Development Engineer interview questions

Initially got a call and told they were interested in profile and I was asked to come to F2F the next morning. It started with a F2F technical round which lasted for about 45 mins. The technical questions asked were related to the skill set interviewed for and was mainly scenario based and performance improvement based. 2nd Round was the coding round where I was given 5 problem statement and was asked to implement the solution. this round took about 1.5 hrs and the 3rd round was again the technical F2F round which lasted for another 45/meeting mins. That was it for the day and there was another F2F discussion after 5 days and this was just the project briefings and expectation settings. After this was the HR discussion which went on for about .5 hours. The offer letter was released after a weeks time.
