Behavioral Technical
I had an online interview with two staff members. They asked me some basic situational questions and then technical questions to check out my thought process. They weren't expecting me to know all the answers, it was more about how I approached the problems. The vibe was super chill and friendly. The whole thing lasted about 45 minutes.

Technical Coding Behavioral
The recruitment process kicks off with an online assessment (OA). After that, there's a Technical round and a Manager round. The OA includes 20 aptitude questions, 10 verbal questions, 20 tech MCQs, and 2 easy-medium coding questions involving basic array and string manipulation. The Technical round is about 1 hour long. The interviewer will dive deep into your projects for about 40 minutes, focusing on 2 of your projects (like Kafka in-depth, NodeJS). They might also ask basic questions about computer networking (like the OSI model, packets), DBMS (keys, normalization, and one SQL query), and OS concepts, plus one basic DSA question (array). It really depends on the interviewer; some friends got asked only 3 DSA questions, some basic OOPS concepts, and just a brief intro to their project. The Manager round is more of a casual chat, asking things like what you'd do if conflicts arose in the team or if a teammate wasn't pulling their weight on tasks.

- Given an array of integers like [1, 12, 13], reverse each number and add it to the array to get [1, 12, 13, 1, 21, 31]. Then, in this new array, count how many numbers appear only once. What's your approach? First, explain how to reverse a number. Then, provide the most efficient way to count the unique occurrences.
- Tell me about your project, especially focusing on your experience with Kafka in detail and NodeJS.
- Can you explain the OSI model?

Coding Technical Behavioral Behavioral
There were four rounds in total. First was a Coding/MCQ Test, which had some tricky questions but were manageable with preparation. Then came the Technical Interview, which felt more like a conversation, involving a good discussion on concepts and scenario-based questions. Next was the Behavioral Interview, also conversational, focusing on past experiences and what could have been done differently. Finally, the HR Interview included an explanation of Telstra's benefits, a general discussion about the package, and reasons for seeking a change.
