- Q1. Let 1=1 2+2=2*2=2 2 ......................................... X+x+x+x+............=x*x=x2 Differentiate on both sides 1+1+1+1.........=2x x=2x explain where did we go wrong?
- Ans.
Explaining the mistake in differentiating 1+1+1+1...=2x x=2x
The differentiation of x^2 is 2x, but the differentiation of an infinite sum is not the sum of the derivatives
The sum of an infinite series can only be differentiated term by term if the series converges
The series 1+1+1+1... does not converge, so it cannot be differentiated term by term
Therefore, the differentiation of the left side of the equation is undefine

Interview Preparation Tips
Experience: This round is the most common round in a general campus recruitment procedure. I have been practising for this round for quite some time, like for 4-5 months. And finally the day came. It was on 1st of September 2016. So it is still fresh in my mind. The test started at somewhere around 2 p.m (as because the number of computers were less than the number of applicants, so we were divided into batches). I was confident enough with the paper as i practised many of them at the time of preparation. We have been told that the paper will be adaptive type. But those who gave the test denied this fact. There were three rounds, aptitude, followed by verbal and logical reasoning. I was tensed at the time of the test as i was fresher and many had expectations from me. Verbal round was easy ( many questions were common with the previous years questions), logical round was easy too, but the aptitude round was a bit tricky. I did some grave mistakes in the aptitude round. So after the test was completed, i was surely not confident with the aptitude portion,(If you are unable to clear one of them, no matter how well you score in the others, you will be rejected). In the evening the results came and luckily i was selected for the second round i.e the technical round.
Tips: KEEP PRACTISING THE QUESTIONS..!! Solve questions online as the final test will be machine based and not written. try to solve the question quickly. If possible, buy an aptitude book and solve questions from there. In the final test, If you can't solve a question, SIMPLY LEAVE it and go for the next question. NEVER EVER TRY TO SEE WHAT OTHERS ARE DOING. Its a grave mistake and can cost you your career. Do your best. Believe in yourself and let your hard work speak..!!
Good luck.!!
Duration: 55 minutes
Total Questions: 55
Round: Technical Interview
Experience: The technical round started at around 10-11 a.m. The interviewer was young and neutral at expression. It wasn't easy to judge how the interviewer was. He started with the default question which was "TELL ME ABOUT YOURSELF". I practised that question for about 1000 times and as expected i nailed it. Then he went through my resume. I had included C,JAVA and DBMS as my skill sets. So the questions were from that portions only. i some how managed to answer them all. But i answered wrong in many of them. Seeing the body language of the recruiter. i was sure that i failed to impress him and i'll get rejected. But at last he asked 2 trick questions and i answered it LIKE A BOSS.!! That was the turning point of my interview and he was impressed with that. My interview was over there and shortly after, i was told that i was selected for the HR round. I was too excited as i was selected for the HR round.
Tips: PRESENCE OF MIND IS THE KEY..!!! No matter how many wrong answers you give. One impressive right answer can get you your job. Recruiter is no machine or God. He is also a man. Be confident, speak well and to the point. If you don't know the answer, at least try once. Don't be overconfident and over smart. Be yourself. Practise Tell me about yourself thoroughly.
Round: HR Interview
Experience: This round is simple conversation round. The HR will ask you question to see what you are. Your behaviour, your body language, your temper, etc, There is no rocket science to crack this round. If you manage to qualify for this round, Consider 90% job done. Be frank, jolly, answer questions to the point. Try to mix up with him. and always KEEP A SMILE ON YOUR FACE. You will definitely qualify..!!
Tips: BE CONFIDENT & BE YOURSELF..!!
General Tips: Start practising for the aptitude round from 4-5 months before the actual test. Practise from various enlisted websites. It helps a lot..!! Believe me. Strengthen your basic concepts. Give only those subjects in your resume with whom you are confident with. Do add your extra curricular activities. It helps.

As i am from Kolkata (one of the most busiest public transport system is here), i said that "Sir i have managed with the public transport here in Kolkata, transport in other city is a piece of cake for me..!!", and we both laughed. :-P
