AXES Interview Pattern

These were selection processes involved :


1. Written test (Aptitude),
2. Technical test (Microprocessor, Data
communications, Operating systems, C, C++),
3. Technical Interview (related to C, Data
Communication, Microprocessor),
4. Group discussion ( Topic : How to develop India ?
The group can choose specific areas such as Education,
Poverty, IT, etc),
5. HR interview (related to personal details).

      In Communications PCM, Quantization, how to solve quantization error, why is modulation required,
      Companding? In computer networks they asked about PING, ICMP, TCP,UDP.
      In Microprocessor, mainly 8086, in detail with programming, and find the error in the program, or the
      amount of memory allocated. Instruction Queue of 8086, memory size required to store 8bit * 8bit
      multiplication. Expect grilling in C programming during interview Even C++

     

AXES  Interview Pattern 

These were selection processes involved :


1. Written test (Aptitude),
2. Technical test (Microprocessor, Data
communications, Operating systems, C, C++),
3. Technical Interview (related to C, Data
Communication, Microprocessor),
4. Group discussion ( Topic : How to develop India ?
The group can choose specific areas such as Education,
Poverty, IT, etc),
5. HR interview (related to personal details).

The information on the interview is pretty sketchy but it may consist of both technical grilling and HR interview The written test is purely technical with stress on Networking, C, Operating Systems, Data Structures etc. You should be clear with the fundamentals of these and other core subjects. Questions are mainly multiple-choice though this may vary.
