The interview process began with a phone interview, followed by two interviews at a branch office conveniently located near my residence. Subsequently, I underwent approximately five interviews in a single day at the main office where I had applied.

The interviews were technical in nature, requiring preparation to solve concrete problems. These could involve coding, algorithm complexity, and system design.

Interviewers had the discretion to ask about topics they deemed relevant. For instance, one interviewer inquired about concrete runtime estimations for a specific algorithm, expecting basic knowledge of typical hardware. Others focused on algorithm complexity, concurrency problems, or what I found to be the most exciting learning experience. If you discuss your previous work, be ready to answer detailed technical questions about it.
