Over few years of navigating countless interviews and refining my craft as a software engineer, I’ve learned some invaluable lessons. These 19 tips can help you stand out. Here’s a crash course that took me years to master but only minutes to share:
Implement WebRTC to Facilitate Direct Video Calls
Understand WebRTC for low-latency, peer-to-peer video calling—a crucial skill for building real-time communication tools.Use Database Indexing to Make Queries Faster
Know how to create and use indexes effectively to optimize query performance in relational databases.Apply Consistent Hashing to Manage Server Loads Efficiently
Learn consistent hashing techniques to ensure uniform distribution of data across servers.Implement Read-Through Caching to Optimize Read Operations
Use caching mechanisms that fetch data directly from the source when not found in the cache.Implement Rate Limiters to Control Traffic Flow
Protect systems from overloading by controlling request rates at application and API levels.Use Inverted Indexes for Efficient Text Searches
Implement this data structure for fast full-text search, especially in large datasets.Choose NoSQL Databases for Managing Unstructured Data
Explore NoSQL solutions like MongoDB or Cassandra for flexibility with unstructured or semi-structured data.Utilize WebSockets for Real-Time Communication
Enable persistent, low-latency connections for real-time data exchange between servers and clients.Use Checksum Algorithms to Ensure Data Integrity
Implement checksum algorithms like CRC to verify data consistency across systems.Deploy Content Delivery Networks (CDNs)
Use CDNs to cache and serve content closer to users, significantly reducing latency.Implement RDBMS for Transaction Integrity
Leverage relational databases to ensure transactional consistency and adhere to ACID properties.Set Up Disaster Recovery Data Centers
Prepare for worst-case scenarios with secondary data centers to minimize downtime and data loss.Prefer Horizontal Scaling for NoSQL Databases
Scale out by adding more machines, and use sharding for RDBMS to handle massive datasets.Incorporate Load Balancers for High Availability
Distribute incoming traffic evenly across multiple servers to improve system reliability.Adopt Eventual Consistency Where Necessary
Balance trade-offs between availability and consistency for distributed systems.Optimize for Low Latency
Combine CDNs, caching, and load balancers to reduce response times for end-users.Use Write-Through Caching with Master-Slave Architecture
Build systems that ensure fault tolerance by synchronizing writes directly to the cache and database replicas.Use Asynchronous Processing with Message Queues
Handle heavy workloads efficiently with tools like Kafka or RabbitMQ for non-blocking operations.Implement Effective Cache Eviction Policies
Use strategies like Least Recently Used (LRU) or others suitable for your system’s caching needs.
Mastering these techniques will not only help you ace technical interviews but also make you a more versatile and resourceful engineer. While it took me years to accumulate these insights, I hope they can accelerate your journey to success.

How i can make interest in coding, Hello guys im shifas from India iam a mern stack intern but I don't have any interest in building web applications so anyone please support and help me!!
Hi Shifas,
From this statement "I don't have any interest in building web applications", I would like to ask a few questions:
How did you get yourself in tech or rather mernstack learning or internship.
