However the interview was about Senior Java Position, I just asked a couple of questions about Java and nothing about Javascript. The interview questions were about: 1. Data structure and algorithms (30 minutes) 2. Operating Systems Concepts (System calls, concurrency, etc, Device Drivers.) 3. TCP/IP Layered protocol ( I was really really good at this when I was in college :) ) Till now about 1 hour or more passed from the 90 minutes interview... 4. Couple of questions about REST, Java Concurrency and Testing I could understand the emphasis on the OS, algorithms design and analysis is to be asked at Google & Amazon-like companies or to be asked to a fresh engineer he is just graduated from the university with a fresh knowledge. I am not denying their questions about OS, Data structure, and algorithms, but to make most on the interview for such topics and eventually got rejected because my knowledge in JavaScript is not enough is not honesty in reporting the Interview status. I answered the algorithms question and OS, TCP/IP from memory (which mostly wasn't that accurate as I left university more than 10 years back).

SQL query to find department wise count
Given a database, where we know some portion of data (e.g. say 20%) is accessed more than the other portion of the database by the client. We have a frontend that client requests data from. Design a data structure that will increase the efficiency of access of objects. And we know that we can only hold on to n elements in memory.
Write a.SQL.query for selecting the second top most salary of an employee from employee table.
You have 16 race horses and a racetrack which only fits 4 horses at one time. Find the top 4 horses in the fewest number of races.
sort an array N consists of four numbers, each number can be repeated k times, where k < n. Example: sort 1111144422223 to 1111122223444. Try to be as efficient as you can, not just O(n^2)
How would you sort an array if you had infinite RAM? Infinite memory?
You have two intersecting linked lists. Describe a function that returns a pointer to the node where they intersect.
Given a big image, how will you pan and zoom into the image in a way so as to focus on the important parts ot the image.
Given an array of unique non-negative integers, {A1,…,An}, and a positive integer, X, write a function that finds all pairs of numbers in the array that sum to X”. You are given an integer array nums sorted in ascending order (with distinct values), and an integer target. Suppose that nums is rotated at some pivot unknown to you beforehand (i.e., [0,1,2,4,5,6,7] might become [4,5,6,7,0,1,2]).” Take a singly-linked list, and reorder in such a way that the first element points to the last element, second element points to second-to-last element, and so on.
