Strive to be Earth’s best employer The 15th leadership principle of Amazon is “Strive to be the best employer on Earth”. 1. How does Amazon explain the principle, what it means? For Amazon, the best employer means someone who employs the best people. Amazon relates this new principle to leadership principle #6, “Hire and develop the best. But it takes the idea in #6, a few steps further. Leaders with their work every day create a safer, more productive, more diverse and fairer work environment.

No one likes a missed deadline, especially not interviewers. However, trying to spin a story that shows it as a success is worse. The interviewer understands that everyone makes a mistake and what they really need to know is what you learned from that mistake. The top 3 things interviewers wish to know include: Accountability for the missed deadline and the reason why you missed it An understanding of how you handled the repercussions of the missed deadline Learnings from the incident and how you improved because of the mistake A sample answer When I was just starting my career as a programmer, I was asked to give an estimate of the amount of time that a particular module would take to be completed.

Anagram An anagram is a word formed by rearranging the letters of another word, using all the original letters exactly once. For example, the word anagram itself can be rearranged into nagaram, also the word binary into brainy and the word adobe into abode. Valid Anagram Given two strings s and t, how do we check whether they are anagrams of each other? One way is to sort both strings lexicographically and compare the sorted strings:

Swap Two Variables In Python, swapping two variables is a one-liner: a, b = b, a. In languages such as Java, swapping requires the use of a temporary variable: 1 2 3 temp = a; a = b; b = temp; If we know the two variables are integers, can we swap them without using a temporary variable? 1 2 3 4 5 6 >>> a, b = 5, 20 >>> a ^= b >>> b ^= a >>> a ^= b >>> a, b (20, 5) It’s a fun little exercise to convince yourself that the above procedure indeed works.

Get all digits in a number with minimum space. Given a positive integer num, the following function iterates its digits from the most insignificant digit to the most significant one: 1 2 3 4 def get_digits_right_to_left(num: int): while num > 0: yield num % 10 num //= 10 Here’s another way to write it using Python’s divmod function: 1 2 3 4 def get_digits_right_to_left(num: int): while num > 0: num, digit = divmod(num, 10) yield digit Can we iterate the digits from the most significant digit to the most insignificant one?

Problem Write a function that takes an unsigned integer and return the number of ‘1’ bits it has. - Example 1: Input: 5 Output: 2 Explanation: Integer 2 in binary is "00000000000000000000000000000101" which has a total of two '1' bits. Example 2: Input: 8 Output: 1 Explanation: Integer 4 in binary is "00000000000000000000000000001000" which has a total of one '1' bit. Brian Kernighan’s Algorithm Notice that for any integer n, doing a bit-wise AND of n and n-1 has the effect of flipping the least-significant 1 bit in n to 0.

Number of Connected Components in an Undirected Graph Given n nodes labeled from 0 to n - 1 and a list of undirected edges (each edge is a pair of nodes), find the number of connected components in the undirected graph. Example 1: 0 – 1 – 2 3 – 4 Given n = 5 and edges = [[0, 1], [1, 2], [3, 4]], return 2.

Introduction In [this post](/posts/a-binary-search-template/ “A Binary Search Template”) we have learned how to use binary search to efficiently find an item in an ordered sequence. In this post we’ll explore problems where the search space is not immediately obvious. If for a condition, condition(k) is True implies condition(k+1) is True, then we can apply binary search. Find the Smallest Divisor Given a Threshold This LeetCode problem asks us to find the smallest positive integer k such that the sum achieved by dividing every number in nums by k is less than or equal to a given threshold.

Introduction Binary search is often used to efficiently locate an item in a sorted sequence of items. Compared to linear search which requires O(n) running time, binary search only takes O(log n) where n is the size of the sequence. Binary search is one of the most frequently asked type of problems in technical interviews. Many candidates struggle when the sequence of items contains duplicates. Template Below is a Python binary search template that works for duplicate items:

Many interviewers intentionally ask the question in an ambiguous fashion to invite clarification questions. Before proceeding, ask the interviewer some clarification questions such as “What should I do if the array is empty” “Can I expect the input to be reasonable?” “Can there be duplicates in the input array?” See also: FAANG Software Engineer Interview If you need to assume something - double check your assumption with the interviewer!

Are you a fresh graduate or an expert developer, if you have not been introduced to Leetcode it can mean 2 things a) you have been in the same company for 7+ years or b) you are not targeting top tier companies. Leetcode is probably the most critical thing you can do as an SDE to land a job at any top tier companies.After training 100’s of SDE’s to get into top tech companies, I have realized that it is not about smarts but it is all about Tenacity and Leetcoding.

One of my candidates recently asked me a system design question in an email.I thought will be nice to document my response and seek advice from my peers who might have interesting practical experiences.I will keep this updated as new responses come by and hopefully we have something interesting. If you are reading this blog and have something to add please email me at rsalota@interviewhelp.io Hi Rahul, Where can I get approximate numbers for the max reads / writes per second supported by various database types ; Relational vs Key-Value vs Column (Cassandra and Hbase) vs In memory (Redis/Memcached).

There are so many System Design Resources on the internet that it is hard to keep track and know which ones to follow and which ones to discard.
