The hardest question that caught me off guard, was when they asked if I was good with conflict resolution and how I deal with conflict.

1 Answers

I said that I am decent at conflict resolution, and that I like to take action from many different angles, rather than force a solution. If something doesn't work, then I'm going to move on and try a different method. Less

Greetings for the day, My first job roll in Wipro BPO was to answer customer queries in regards to medical insurance claims and also describe the benefits and eligibility of the health insurance as per the policies the customer is entitled to. My second job involved detection of credit card frauds. Once I find an on going fraudulent activity on a customer's credit card, my responsibility was to cancel and reissue a new card. Next, in Teleminds and Clarus, my job description was to troubleshoot internet and phone issues. Added to troubleshooting, I also helped the new customers set up there phone and internet. Customers in these two organisations were located in Australia. Other than troubleshooting, I also took care of the billing queries and also the logistics requirements of the necessary hardwares required to set up the internet. Lastly, in my present organization Commscope, my work is to take care of the issues raised by the customer via tickets and also answer chats and calls. The prime work is to ensure the licensing on the physical and virtual controllers, switches and access points. Secondary to this, I also need to work on the logistics of any hardware, that needs to be replaced, to keep the internet services uninterrupted for home and business customers. Less

so is the answer 4 heat 1 (first 4 car) + 1 (4 second set) + 1( Top 2 from first + Top 2 from second set) + 1 (3 car heat among the 3rd placed car) Less

Only two races of four cars in each. Get the times of all cars and sort them. You don't need any more races because the times will be the same in subsequent races. :) Less

What port does ftp use? (That seemed like a trick question because they only wanted one port)

7 Answers

In FTP, Port 20 is used for the data whilst port 21 is used for commands

Port numbers 21 and 20 are used for FTP. Port 21 is used to establish the connection between the 2 computers and port 20 to transfer data. Less

20 (data) & 21 (commands) for regular ftp, 989 (data) & 990 (commands) for ftps. not sure why they want 20 though since the first connection is typically established on 21, unless they're specifically troubleshooting why data isn't being transferred Less

What are the packets sent in a TCP connection?

6 Answers

Syn // Syn - Ack // Ack

It's either you are so confused with the question or that question actually is very vague. It is not very clear. It seems that's obviously not the actual question you heard. The interviewer is probably asking "What are the information is in a TCP packet?" - This question makes lot of sense. Less

Whoever answered it with a 3 way handshake (SYN/SYN-ACK/ACK) does not know what the question is about. Less

You work on 60th floor of 100 story building. You walk into your office and find a bomb sitting on your desk. It reads 90 seconds and is counting down. What do you do?

5 Answers

I would keep calm because it is obviously a fake bomb. Bombs with big countdown displays only happen in the movies. Less

Pull the nearest fire alarm to get people out of the building as quickly as possible, then get the bomb to a corner and place myself on the opposite side of the floor (or inside a fire escape, which is thicker than drywall) Less

I will go the top of the building (roof) , which might take maybe 60 seconds (assuming the lift is not too slow), and when 6 seconds are remaining, I will throw it diagonally away (as high as I can and as far from the building as I can) so that it explodes Mid air which significantly reduces the probability of any kind of damage or loss.
