Tech Screening:

• Format: done over the phone or video call.
• Focus: This part checks your ability to solve problems and code through algorithm questions and technical talks.
• Purpose: To gauge your basic coding skills and how you tackle problems.

On-Site Interviews:

• Format: Several rounds including:
  • Coding Interviews: You’ll need to solve hard problems on a whiteboard or computer.
  • System Design Interviews: These look at how you design systems that can grow and work well.
  • Behavioral Interviews: They check if you’re a good fit for the company and assess your people skills.
• Purpose: To test your tech skills, problem-solving, and how well you’d fit in.

Cultural Fit Assessment:

• Format: Part of behavioral interviews.
• Focus: Check how well you match the company’s values and workplace.

How to Get Ready for Everything

Nailing Your Coding Skills

Key Data Structures and Algorithms

• Arrays and Strings:
  • Key Concepts: Handling putting in order, looking through.
  • Common Problems: Finding two numbers that add up the longest string without characters that repeat.
• Linked Lists:
  • Types: Lists linked one way, two ways, and in a circle.
  • Key Operations: Adding taking out, turning around.
• Stacks and Queues:
  • Uses: To figure out expressions, to plan tasks.
  • How to Make: With arrays or linked lists.
• Trees and Graphs:
  • Tree Types: Trees with two branches, trees for searching with two branches, AVL trees, and trees that are red and black.
• Graph Algorithms: BFS DFS shortest path (Dijkstra’s algorithm), minimum spanning tree (Kruskal’s and Prim’s algorithms).
• Hash Tables:
  • Concepts: Hash functions ways to solve collisions.
  • Use Cases: To store and retrieve data, to index information.

Advanced Topics

• Dynamic Programming:
  • Techniques: Memoization tabulation.
  • Common Problems: The knapsack problem longest common subsequence.
• Greedy Algorithms:
  • Concepts: Choose the best option at each step.
  • Examples: Activity selection, Huffman coding.
• Backtracking:
  • Concepts: Build solutions step by step and drop them if they fail.
  • Examples: N-queens problem, Sudoku solver.

Resources to Practice Coding

• LeetCode: Has a huge selection of problems, practice interviews, and company-specific tests.
• HackerRank: Gives you coding challenges and competitions to check your abilities.
• CodeSignal: Includes timed coding exams and evaluations.

Books to Read

Doing Great in System Design

Key Concepts

• Scalability:
  • Concepts: Scaling up vs. scaling out.
  • Strategies: Splitting workload and dividing data.
• Load Balancing:
  • Types: Taking turns picking the least busy, using IP addresses.
  • Tools: Nginx, HAProxy.
• Caching:
  • Concepts: Storing in computer memory vs. spreading across machines.
  • Tools: Redis, Memcached.
• Databases:
  • Relational (SQL): PostgreSQL MySQL. They focus on organizing data ensuring data stays correct.
  • Non-relational (NoSQL): MongoDB Cassandra. They focus on flexible data structures and data that might not match right away.

Practical System Design Examples

• Design a URL Shortener:
  • Components: URL mapping unique ID generation, redirection service.
  • Considerations: Handle collisions, scale, and track users.
• Design a Social Media Feed:
  • Components: User profiles, posts, feeds, notifications.
  • Considerations: Update in real time, store data, and retrieve data.

Resources for System Design

• “Designing Data-Intensive Applications” by Martin Kleppmann: Looks into modern system design and ways to manage data.
• System Design Primer on GitHub: A complete guide with real-world examples and tried-and-true methods.

Getting Ready for Behavioral Interviews

The STAR Approach

• Situation: Paint a picture of the setting or background of your example.
• Task: Spell out the challenge or duty you had to deal with.
• Action: Break down the steps you took to tackle the situation.
• Result: Talk about what happened because of what you did.

Typical Behavioral Questions

• “Tell me about a time you had to get over a big hurdle.”
  • Focus: How you solve problems and bounce back.
• “Give an example of when you had to work with a tricky teammate.”
  • Focus: How you work in teams and sort out conflicts.
• “How do you deal with tight deadlines and high-stress situations?”
