Hi Folks

So ready for IBM. I am feeling pleasure to share my experience with you. Myself ,Bhawna Pant, have completed my B-Tech (2012 Batch ) with specialization in ECE.

81*2=162  so,ans = 64*2= 128

3) 1, 1, 2, 4 , 6, 36, 39, 1521, ?
1+1=2
4+2=6

Aptitude Questions: No need to prepare whole book. Prepare only:

1) Time and work
2) Time and Distance
3) Percentages
4) Averages
5) Ratio and Proportions

Believe me very basic questions. You can easily hit 10 out of 18. The mail concern is timer. It gives you 2.15 minute for each question. After 2.15 minutes question will automatically remove from the screen.

I cleared this round very easily.

Round 2: English Assessment Test

1) Punctuation ( TIME Material) : I read only three pages of rules of punctuation and hit all questions right. You need to know the correct use of comma, colon, semicolon, apostrophes.

2) Business Letters and Business Emails : Like should we user smiley in business mail, should we write "Hi" in business letter. Very very basic questions.

3) Salutation : Read from internet. This will be enough. Like We should use " Dear President John Smith " in place of "Dear Mr. John Smith". Find salutation topic from web and read all the rules. It won;t take more than one hour to prepare.

I have cleared this round too. Result came in Email at 2.00 AM on next day.

Round 3: Group Discussion

The easiest round for me. My topic was " How do we learn in Life- via experiences or examples". You need to give a strong starting and strong ending. You should have confidence. We were 12 in a group and we all were selected. Yes it is possible. Don't think you are inferior in communication to others. Make your voice bold, try to use strong sentences and GD will be yours.

Other topics:

1) Smartphones or Tablets
2) Social Networking
3) Women Empowerment
4) Computer Education is necessary or not.

blah blah blah, very general topics.

Cracked that round. Felt happy.

Round 4: Personal Interview

I was lucky. HR was a lady and she didn't ask any technical question. She gave me a logical question. "If I become a Team Leader how will I get the work done within 3 days if it would actually take 6 days to complete."

Guys PI is like a water. You can give it any shape. Do not write anything in resume for which you are not prepared. Do mention your previous job work and final year project. On introduction, give details of your previous job so that HR will ask only those things.

Well this also depends upon HR to HR. I am very thankful to her who interviewed me.

Result was announced within 45 minutes and I was there on the list of selected candidates. Felt proud. I was not from a very renowned college but I did this cz I wanted to crack this. I called to my mom, dad and bhai. They all congratulate me. I can say it was the happiest day of my life.

Finally we were called to fill Employment form. Now I am waiting for my joining call. Hope I will get it soon. Proud to be an IBMer.

All the best to all of you. Hope we will meet in IBM someday.
