My experience in IBM GTS- ATO ROUNDS:
ROUND 1:
as you all know for GTS-ATO the first round is quant,it consists of 18 ques, If you want to be more confident then solve m4maths numerical ability bits of IBM.Only some questions will repeat but all models are from M4Maths only..........
ROUND 2:
In this round they are conducting like personal interview for 1 to 2 mins thats it.But the key point to be noted here is they are just checking your spontaneity and fluency(you need not be that much fluent, just manage speaking for atleast 30 to 60 sec)
for me he asked(Internet & Tiger)
3.TR AND HR:
It totally depends on the hr you've got as well as ur technical knwoledge related to Networks also.......
For me the ques were
1.Tell me about yourself
2.project explanation , your role in it , any problem u have faced and how u managed it
3.PPT Explanation and a ques like
How you will manage a crowd to listen to you while you are presenting your ppt??(so many cross questions)
4.Hobbies
5.strengths( better prepare 2 examples beforehand )
6.I.P.address,Network,Protocols,HTTP,Linux commands etc...everything related to network basics only.
Thats it !!! WISH U A GOOD LUCK..............
