Four interviews were performed. The first one was to design a coffee shop company. The second was about OOP to create a model of a parking lot. The third was a behavioral interview. The fourth was a coding exercise to decide if parentheses were valid.

2. Create models for a parking lot system.

3. Some behavioral questions, such as: "Why should we hire you?", "What have you learned recently?", and "What would be your advice for someone studying your department at university?"

4. Decide if parentheses are valid or not.
