### If you were asked to unload a 747 full of jelly beans, what would you do?

Assuming they are loose jellybeans, and their unloading needs to be managed rather than just dumped on the tarmac ... Start by phoning the people at the other end, of the process. They managed to load an entire plane with jellybeans! Any group that can figure out how to fill a plane with jellybeans may be a big help in undoing this mess. Less

Put an ad on craigslist "Free jellybeans - won't last. Hurry!". They'll all be gone in no time. Less

I would do it. The question is not "how" you would do it.

### Why are pot hole covers round and not square?

It makes sense to make them round because they can not fall through if ever accidentally uncovered. If squeare =&gt; the lid falls in diagonally. Less

So that if someone mistakenly drops it in on its side it won't fall into the hole. A square cover dropped mistakenly diagonally on its side would fall in. Less

Its because the round shape causes the impact of cars and trucks to be distributed evenly. If it was square, the impact would be highest at the corners causing the cover to break. Less

### How many unique handshakes if each person in a group of 10 give handshakes out to each and every other individual. (a) 100 (b) 50 (c) 45 (d) 20 (e) 10

true, or 9+8+7+...+2+1

None of those answers are correct. The follow-up question should be are we assuming that each person is only using 1 hand? For example, if everyone is only giving handshakes left to left, or left to right or right to right or right to left? Granted left to right and right to left would be awkward. Less

45. Imagine it as a polygon of side 10. Or draw out triangle, square, pentagon, and see the pattern yourself, if you don't know the algorithm. Less

### You get an hour to prepare for a case study - and delivering your ideas on a white board. After the hour is up - you present your case to a manager. The case study was not "difficult" but rather lengthy. I did not have enough time to finish everything I would have liked to. Be prepared to get your most valid points out before diving into the details - and read the entire case study before starting. Some important information lies at the end of the case study document.

in a short time presentation the base of the topic are most imprtent then it's whole explanation,and every topic is start from a small point i.e the mening of that presentation title. Less

### Where do you see yourself in 5 years

Wants to be leader with engaging people and technology

▲ 1 ▼ Wants to be leader with engaging people and technology for the nations. It will be look much better when my position or I will be Leader. Less

### How to find whether a linked list has a loop within it.

Use 2 pointers, varying the speeds of both. If at sometime they meet each other, that means there exists a loop, else if the reach the end of linked list that means there does not exists a loop. Less

The previous answer has an indefinite worst case running time, which usually is something you want to avoid. You can search through the list once adding the pointer addresses to a hashmap. If ever you reach an address that already exists in the hashmap, then there is a loop. In the worst case you have to read through the whole list once. On average, you have to read (n+1)/2 elements. Less

While traversing the list from the starting node, you can leave a mark behind, if you encounter a mark in a node, then it's linked. If you reach the end without finding your mark, then it is not linked. Less

### Design an efficient algorithm that checks if a LinkedList, that holds a trillion elements, is circular or not.

I feel like this is very simple, but my solution is expensive memory-wise. Simply make use of a hashset and add elements as you iterate through the list. If you have a hash collision, there is a loop. Less

Make two pointers that will through the array the first one jumping one step and the second two steps each loop. If they ever meet again that means it's circular. Less

### How will you balance your family and home life with working a night shift?

I don't think that question is legal. You're not supposed to factor in family and personal factors in your hiring decisions, the candidate isn't even required to disclose the fact he/she HAS a family. Less

Working night shift means I am there during the day to help with child are and house work what is brilliant. I am also taking additional supplements to support my body during this change and of course I have specific times to sleep. It's great!!! Less

I don’t have a family it’s only me so honestly won’t be a problem

### The IT manger asking things that are not in common, like what is the results of using a less than one meter network cable !!

I think that's stupid

i think it's an ad-hoc network !

1- Connecting any System to a nearby network socket ( wall or switch ).. 2- Using it as a batch cord in the network patch panel.. Less
