Java and Selenium Mock Interview for Experienced Candidate | Automation Testing/ SDET

11/28/24
Summaries by topic
English

This mock interview assesses the candidate's Java and Selenium knowledge through a series of questions covering core Java concepts, inheritance types, exception handling, constructors, class relationships, interfaces, and the Math class. The candidate demonstrates a solid understanding of these topics, with proficiency in Java syntax and object-oriented programming concepts, leading to a successful mock interview.

Java Data Types

00:00:15 The interview starts with a basic assessment of the candidate's knowledge of Java data types, including primitive types like byte, short, int, long, float, double, char, and Boolean, and reference types such as String.

Inheritance Types in Java

00:01:00 The discussion transitions to inheritance in Java, with the candidate outlining five types: single-level, multi-level, hierarchical, multiple (via interfaces), and hybrid. The candidate explains each type, including the keywords (extend/implements) used to achieve them.

Exception Handling in Java

00:03:17 The necessity of exception handling in Java is explored. The candidate explains that it prevents code from stopping abruptly due to unforeseen exceptions. The candidate highlights the usage of try and catch blocks to manage exceptions.

Constructors in Java

00:05:00 The conversation then shifts to constructors in Java, which are special methods with the same name as the class and no return type. The candidate explains that constructors can be overloaded but not overridden and elaborates on the reasons for this behavior.

Class Relationships in Java

00:05:39 The candidate demonstrates understanding of class relationships in Java, outlining how to create relationships between different class types, including class to class (extend), class to abstract class (extend), abstract class to abstract class (extend), and class to interface (implements). The candidate also notes the impossibility of certain relationships such as interface to class.
