It started with friendly HR interview it took a half hour, she just asked the usual questions like introduce yourself, where you worked ..etc After that I started with a tech interview with the team leader and It was so rich interview, the interviewer asked me in everything OOP, design patterns, SOLID principles, Mysql queries and performance, algorithms..etc, and it took like two hours, but it was so friendly one. Finally, I talked with the tech leader for 10 minutes in general tech topics and that's all.
