Leetcode Preparation Strategy For Google interview






🚀Preparation Strategy For Google interview Leetcode:




  1. Incorporate daily Leetcode challenges into your study routine to improve consistency and expose yourself to a wide range of problems.

  2. Focus on the top 100 questions by frequency to familiarize yourself with the most commonly asked questions.

  3. Utilize the top 75 LC-curated questions for additional practice: https://lnkd.in/dD5MmEks

  4. While these questions may be rated as hard, it is recommended to start with easy/medium ones to build a solid foundation. Additionally, practice mock interviews to prepare for real-life scenarios.

  5. Target Leetcode questions that are tagged with Google to gain insight into the types of questions commonly asked by the company.

  6. Utilize the Cracking the Coding Interview book as a resource to supplement your learning.

Tips:

  1. Attempt to solve a problem on your own, even if you are unsure of the optimal solution.

  2. Analyze the time and space complexity of your solution, and identify areas that can be optimized. Consider alternative solutions or data structures.

  3. Review Leetcode solutions and the discussion section, but try to implement the solution without looking at the code. This will help you truly understand the concept.

  4. Aim to improve the runtime of your solution to beat 90% of other solutions.


System Design:

If you are targeting Google, it is a must to read the book DDIA. Additionally, the book "System Design Interview" by Alex Xu and "System Design Primer" by Donne Martin are also recommended. For further learning, take the courses "Grasping the System Design" and "Grasping the Advanced System Design."

In terms of behavioral skills, it is important to understand various leadership principles. To showcase these skills on your resume, use the STAR approach to write stories that highlight attributes such as taking the lead, resolving conflicts, and dealing with ambiguity. To prepare for interviews, make sure to read, rehearse, and repeat your stories.

For time management, set aside approximately 2 hours on average during working days and 4-5 hours on weekends/holidays to focus on technical skills. Make sure to cover topics such as UnionFind, Trie, Cycle Detection, Intervals, Segment Tree/Fenwick Tree, Graph distance, Randomisation problems, Topological sort, DFS/BFS, 2-D Matrix Prefix Sum, and Dijkstra/Bellman Ford/Floyd Warshall/Kruskal's Minimum Spanning Tree. With this approach, you can gain new knowledge and boost your confidence.

A Galaxy of Misfits: Why We Fell in Love with the Guardians of the Galaxy

  If you rewind the clock to early 2014 and asked the average moviegoer who the " Guardians of the Galaxy " were, you would have likely been met with a blank stare. At the time, they were a C-list comic book team operating on the fringes of the Marvel universe . The pitch sounded more like a fever dream than a guaranteed blockbuster: a 1980s pop-culture-obsessed thief, a green-skinned assassin, a fiercely literal warrior, a genetically modified talking raccoon, and a walking, fighting tree. It was widely considered Marvel Studios' biggest gamble. Yet, when the lights went down and Blue Swede’s “Hooked on a Feeling” blasted through theater speakers, that gamble paid off in astronomical ways. The Guardians didn't just succeed; they redefined the modern superhero genre , proving that audiences were hungry for something weirder, wilder, and fundamentally more human. Here is a deep dive into how a ragtag group of cosmic outlaws stole the galaxy's heart—and ours. The Ro...

How do I write a C program to find the factorial of a number?

  Finding the factorial of a number is a common problem in computer programming. A factorial of a number is the product of all positive integers up to and including that number. For example, the factorial of 5 is 5 * 4 * 3 * 2 * 1 = 120. In C programming, we can write a program to find the factorial of a number using a loop. Here's an example program: c Copy code # include <stdio.h> int main () { int num; unsigned long long fact = 1 ; printf ( "Enter a positive integer: " ); scanf ( "%d" , &num); for ( int i= 1 ; i<=num; ++i) { fact *= i; } printf ( "Factorial of %d = %llu\n" , num, fact); return 0 ; } In this program, we first declare the variables num and fact . We then prompt the user to enter a positive integer using the printf() and scanf() functions. Note that we use the unsigned long long data type for the variable fact because the factorial of a large number can become very ...
