IBM Interview Questions

These are latest Interview Questions which I occurred these days in IBM

Technical - 1
1.       Tell me about yourself? ( which is common question )
2.       Tell me which technologies you have used up to now and how can rate yourself on these technologies? ( The next Questions will be asked on this rating. So, plan it and answer )
3.       Tell me about your project? Think I am your customer and came to you. You need to explain how you can explain?
4.       What are the roles and responsibilities you are handling day to day life?
5.       Tell me the your project architecture?
6.       What are the testing processes which are considered for your project?
7.       Where the clients have faced any problems on which you have developed? Can you explain
8.       Scenario: you have two arraylists as al1 and al2, as shown in below
al1(arraylist object           al2(arraylist object)
e1(employee object)     e1(employee object)
e2                                           e2
e3                                           e3
e4                                           e7
e5                                           e6
Here we are adding employee objects(e1,e2,e3,e4,e5) into al1 of arraylist and employee objects(e1,e2,e3,e7,e6) into al2 of arraylist.
Now you have to compare two objects and you have to delete the common objects such as (e1, e2, e3) in al1 and at the last there should be only e4 and e5. How could you write the program?
