Its a 3 stage process. Stage 1: Aptitude Round Its a very basic aptitude round with common questions that float around in all companies. There are in total 29 questions from aptitude and on C++ program which is generally on string handling. You just need to have 15 apti questions correct and the program to get through. Stage 2: Technical Round It will take a lot of waiting. When your turn comes be confident and tell your strength as C++(not C). Nothing else required. They will ask you very basic C++ questions like OOPs concept and difference b/w C & C++. Then they will ask you to write one program(only one) on Data structures( Singly/Doubly LL or Queues at max), you get that correct, or just write the code and explain the logic correctly and you are through. Then you will be approached and be told you are selected and will have one final interview at client location(Huawei). You will be told about the bond(2 years, 1.5 lakhs) and you have to submit your marksheets. You will be told about the salary(pretty low). If you agree you will then have to wait for a client interview call(one week). This all was the easy part and the process will take one full day. Stage 3: Client interview This is the tough part. Here you will have two interviews. Based on your skills and requirement in Huawei you will face First interview with a team lead. Here it doesn't matter how you performed at Ionidea. They will take interview as per their requirement. You would be asked about Unix, SQL(brush up the basic topics) and C++ programs(3-4). If you do even average you will face second interview with your going-to-be-reporting-manager. They will again ask you some Unix, SQL and C++ questions(basic level). The you will have to write 2-3 programs on data structures. Then you will be asked few puzzles(4-6) which pretty regular which you can get just by a google search. Its good to know a thing or two about Huawei(what it does) in advance. If you are uptill here, you are pretty much selected
