Two Sum. Then follow up three sum

There is a web page which shows us a table which has products against their price, tax, discount, delivery time. There are about 20 products. There is a Database which has these same things. In your Selenium Test Automation Framework, how will you cross verify what is shown in the webpage correctly maps to the DB values for that product? Or just tell me how will you solve this problem, no need to write the code.

You are using a Webmail UI like GMail. You have to send a "Hello" mail to a person.

1. Write all the scenarios which you would cover in an automated test framework.
2. If you have to test it for 50 different users, what are the challenges you might face in writing your test scripts?

It seems like a pretty easy solution. But at the end he said I need to answer based on the amount of experience I have. I have 9 years of experience as a QA. And he wanted me to give a solution like I actually have 9 years of experience. In short, I blew this question.

You have been given a map which holds book name and book author. One author might have several different books. But books are unique. Now, write a function which will return you a Map which will have the author name as unique and all the books he has written as values.

Book Map=["Java"-->"John", "C#"-->"Rob", "Ruby"-->"John", "Rails"-->"Rob"]

This should return a Map which has the following:

["John"-->{"Java","Ruby"}
"Rob"--{"C#","Rails"}]

Multi -level cache system design with different storage in each level.
Read Operation : – Minimum time to read a particular key from cache system. This should be followed by writing the key in all levels above it. Eg. if “key” is found at level ‘i’, add this key to cache present at 1 to i-1 level.

b. Write Operation: – Any write Operation should write in cache of all levels.

You can choose any algorithm for cache management like LRU, MRU.

Given a map represented as a 2d array with only 0’s and 1’s. An island is a group of connected 1’s. Find out how many distinct islands(can be rotated).
eg:
1 1 0 0
1 0 0 0
0 0 0 1
0 0 1 1

return 2.

You just take a pinch and rub it at the tip of your organ at least 30 minute's before being intimate. You know it’s working when you start feeling some heat down there. When that happens you can have a session that lasts up to an hour before you ejaculate
A sachet can be used for two or three times depending on the size of the organ.”
A 57-year-old from Australia, told me to shared his experience with the product. Different women where disrespecting me in bed but he said the moment he used the substance their was a change with different women he invited.
“After applying the powder on my organ, I waited for about 30 minutes before my private organ started feeling itchy. That is when I indulged in the actual act.
“My organ was not only erect, it looked swollen. On that day I went for about 30 minutes without reaching a climax and my partner ended up complaining because she had reached orgasm twice and was tired.
Men now using Congo dust for sex: This will definitely make her cry in bed
This is a sex performance enhancing powder for male who want to kiss goodbye to Early Ejaculation, Low libido Weak Erection and failure to do more than 1 round. Stop using mutuba seed because it doesn't work.

Design a system like HackerRank/Codechef.

How is code review done?

How is design review done?

Given disjoint set of intervals and a new interval.Merge them and generate the resultant intervals, Write Code
E.g input is input1=(1,5)(10,20)(25,100) and input2=(6,8)

you have a function to set particular pixel to black set_pixel(x,y) will set x,y to black Now, given center of circle(a,b) and its radius r, all integral you need to set suitable pixels black

Because Ethereum smart contracts are deployed publicly, anyone with the right tooling can read their contents.
Furthermore, people can access any state the contract specifies. Knowing that people have access to your
validation code, how do you write the contract so that somebody *must solve the problem. (*it should be near
impossible or significantly computationally expensive to derive the answer from your contract code)

Ethereum is a blockchain that can run arbitrary programs. Write an ethereum program (i.e. contract) that will send 0.1 ETH (a bounty) to the first person who gets the correct answer to the above "100-digit"
question.

Here is a standard telephone keypad:
1 2 3
4 5 6
7 8 9
* 0 #

Write a program to calculate the number of n-digit numbers that simultaneously:
● exclude * and #
● start with 0
● are formed by cycling through three moves: a "tall L" (two steps in one direction followed by one
step in the perpendicular direction) followed by two "short L"s (one step in one direction followed
by one step in the perpendicular direction).
For example, the qualifying 2-digit numbers are {04, 06}, the qualifying 3-digit numbers are {042, 048,
062, 068}, and the qualifying 4-digit numbers are {0424, 0426, 0484, 0486, 0624, 0626, 0684, 0686}.

How many qualifying 7-digit numbers are there? How many qualifying 100-digit numbers are there?

Given an array of int with less than 75 elements ( random, no bucket) . make all duplicates 0 and print array in sorted order .
avoid using any extra space, or any sorting algorithm ( quick sort , merge sort)

example :
input :
6 1 1 22 9
output :
0 1 6 9 22

Any Optimized Solution to avoid TLE for 4 test cases. I have tried by implementing Stack using Doubly Linked List.
Still not able to pass test cases!!!

Design a concurrent hashmap.

Please point me to the link if this has been discussed before.
They wanted design with code snippet of the classes.

Given lat long of cabs in a city(lat long keeps changing)
Implement a function getNearby(lat1,long1) which returns all cabs in a circle of radius R from lat1,long1.
Which datastructure will u use?
FollowUp qs: Hows it implemented using a database like MySQl or Postgres.

Given a BST of memory sizes. Find best fit for a memory block of size M.

Given a wall, which is made up of two types of bricks (Porus / opaque ). Porus bricks allow water pass through them. Opaque won't. Find whether water reaches to ground, if there is any rainfall.
Water can flow from top to bottom, diagonally, horizontally as well. Only flowing from bottom to top is not possible.

Given an infinitely large array and every element has tags associated with them, and there are about 10,000 tags (say) then sort the given array to get all tag-0’s first, tag-1’s next and so on in O(n).

Given a 2-d integer array, find the size of the largest connected area (number of elements connected), where two elements are connected if they are side-adjacent in matrix(up,down,left,right operations). Also there can be maximum of two different integers present in this set.
