• Java 11 knowledge – in and out
• Vert.x or Spring 5 based Reactive programming
• Couchbase is an added advantage
• Why using Postgres and not MariaDB/MySQL (one reason could be enterprise unavailability)
• Why using Kafka – can we solve that same problem with other messaging queues?
• Clean code principle
• KISS (Keep it simple and stupid) – why it can be a choice while designing a complex system
• Debugging do’s and don’ts
• SOLID principle – specially Liskov’s substitution principle – How it can be a game changer
