how would you design how a cellphone implements its contact list when you press a certain letter. For example, If you press M it will tell you all the names starting with M. then if you press MI it will tell you all names starting from MI and so forth....
We have a log file, can grow pretty big. Each line is a trace-log, and the first field is the RequestID. We need to scan the file, and print all the logs for requests which resulted in error .. 001 <timestamp> BEGIN 001 <timestamp> fetched from db 001 <timestamp> some processing .. 002 <timestamp> BEGIN .. 002 <timestamp> fetched from db 001 <timestamp> returned success 003 <timestamp> BEGIN 001 <timestamp> END 003 <timestamp> some work 002 <timestamp> ERROR 003 <timestamp> some other work

Short coding : 1. They gave an array A with N elements we need to find if addition of two elements in the array will be the element K Ex: I/P: a[5]={7,3,2,6,4,} K=10; Op:7+3=10 6+4=10 2. Two sorted array a[],b[] will be given we need to merge the array without temporary array. 3. An array arr[] with elements are given we need to sort the odd number in descending on left side and the even numbers in ascending on the right side of the array Ex: I/P: arr[5]={7,4,3,5,2} O/P:7 5 3 2 4
question mostly about output prediction of java code
You are given an array of integers, a1, that have sequential integers 1 through n. ( { 1,2,3,4,5 } or { 1,2,3 } or any other array) You are also given an array of integers, a2, that also have numbers 1 through n, but are not in sequential order and are missing one of the numbers between 1 and n. Find the missing number in a2. Did you check for special cases? Can you do this in O(n) runtime?

whats the angle between the minute pointer and hour pointer at 3:15
Puzzle1 - Given 8 coins, and the fact that one of the coins is heavier than the other, how many times(min) do you need to use a beam balance to figure out which is the anomalous coin? After I answered this, he made it little tougher. Given 9 coins and one anomalous coin(maybe heavier or lighter), figure out which coin it is and whether heavier or lighter. What is the min no of comparisons? This is where i took a while to answer.
