Three primary areas were covered: i) Thread related question. Their product is Thread based so expect good amount of questions here only. ii) Coding : not much was asked to write the code but some basic C/C++ constructs were asked iii) domain knowledge: 4G call flow related question.s

It was final round, It is very sad that after spending 4-3 days on this interview and specially prepared for this interview and specially took time for doing a poc usnig WebRTC (whcih i havnt had knowledge even though took it as opportunity) even then i have got such a worst feed back from the interviewer. Interviewer has given me the fed back that" Along with UI/Ux skills, we are looking for someone with good knowledge and recent practical experience in Rx Java, database and file handling skills. Someone who can own and work independently on app module. Although you have answered most of the questions but considering your experience, I found you little lagging in these areas." I had answered so confidently with different use cases and taking into account the effecient coding guidelines. that was pretty straight forward. I havnt answerd to quetions whch i hadnt wotked or not a part of my area, and even he not asked on such toipics I dont understand one thing the interview went for 1 hour and 5 min of Nw disturbance was there in that, rather then that it was quite an easy interview for me to go through, cos i knew on my work experience how i have give the correct answers. IF HE WAS NOT OK WITH MY REACT PROGRAMING EXPERIANCE EVNE HTOUGH I TOLD I HAD WORKED FOR 5 MONTH IN PREVIOUS PROJECT THEN WHY HE CONTINUED THE INTERVIEW???? HE WOULD HAVE DROPED THE INTERVIEW THERE ITSELF.? I too have took interview however never played with candidates emotions and time. More over i Felt something wrong with this interviewer technical skill set when he asked a qutetion with scenario which was not an efficient way of programming, He should be aware that candidates don't come to INTERVIEW FOR GRANTED. TOTALLY DISAPPOINTED !!! think ten times before going for interview on confirming WHAT ACTUALLY THEY ARE LOOKING FOR..

I reached Mavenir system by 11 am. After 20 min HR came and asked me write a technical paper consist of 20 questions in 1 hour. There were question related to C++ - exception, virtual function, down casting, doubly link list, template etc. Second round for technical and lasted fir 2.5 hours. Third round was technical manager round. He asked technical questions and took 45 min. Worst part was that he asked me leave immediately after interview without telling me status and HR did not come to me again.. I am still shocked...I came out at 5.15pm.. I gave answer of 99%*questions. No idea why I was rejected. What did not like in 6.30 hours long interview?
