4. Measuring System Capacity and Performance Requirements
5. Why Practice is Key to Coding Mastery
6. Efficient Problem-Solving by Sorting Input Data
7. Database Replication Explained: Single-Leader, Multi-Leader, Leaderless
- Scalability Approaches: Server Clones, Functional Partitioning, Data Partitioning
https://lnkd.in/eXGm8MBC
9. Tackling Coding Interviews: Arrays and Strings Tips
10. Database Sharding for Scalability and Availability
You Should Know:
1. System Design Commands & Tools
- Use `htop` or `nmon` to monitor system performance in Linux.
- Test API latency with
curl -o /dev/null -s -w '%{time_total}\n'</code>. </li> <li>Simulate load testing using Apache Benchmark: [bash] ab -n 1000 -c 100 http://test-server/
2. Space Complexity Analysis
- Check memory usage of a process in Linux:
ps -o %mem,cmd -p [bash]
- Profile Python memory with
memory_profiler:@profile def my_func(): a = [bash] 1000000 return a
3. Database Replication (PostgreSQL Example)
- Set up replication:
-- On Primary ALTER SYSTEM SET wal_level = 'replica'; CREATE ROLE replicator WITH REPLICATION LOGIN PASSWORD 'password';
- On Replica:
pg_basebackup -h primary_ip -D /var/lib/postgresql/ -U replicator -P -v
4. Scalability Testing
- Use `k6` for load testing:
k6 run --vus 100 --duration 60s script.js
- Docker Swarm scaling:
docker service scale my_service=10
What Undercode Say:
Technical interviews demand both theoretical knowledge and hands-on expertise. Mastering system design, algorithmic efficiency, and database optimization requires continuous practice. Use Linux/Windows commands (strace, perf, Wireshark) to debug performance bottlenecks. Automate repetitive tasks with scripting (Bash/Python) and simulate distributed systems locally using `Docker Compose` or Kubernetes.
Expected Output:
A structured guide with actionable commands, tools, and best practices for software engineering interviews.
