Interview
The overall experience exceeded expectations due to the exceptional attention to detail, consistently professional communication, thoughtful execution, and impressive reliability throughout the entire process. Every aspect was handled efficiently, resulting in a seamless, highly satisfactory outcome that demonstrated both expertise and a strong commitment to quality.
Interview was conducted well. Questions were fair, just wasn't prepared well enough. Brush up on your data structures and basic algorithms. The programming language used doesn't matter. Prepare past experiences stories beforehand so you are ready when asked about an experience.
