1. Resume Screening The process often begins with the recruiter or hiring manager reviewing resumes to shortlist candidates based on qualifications, projects, internships, or coursework relevant to the role.

2. Online Assessment (Optional) Format: A coding test administered via platforms like HackerRank, LeetCode, or CodeSignal. Focus Areas:

• Data structures (arrays, strings, linked lists, stacks, queues, hashmaps, trees, and graphs).
• Algorithms (sorting, searching, recursion, dynamic programming, etc.).
• Basic programming skills (syntax, logical thinking, and code efficiency).

1. Phone Screen / Virtual Interview Duration: 30–60 minutes. Interviewer: An engineer or technical recruiter. Components:

• Technical Coding Questions: One or two coding problems, often done on a collaborative platform like CoderPad or Google Docs.
• Behavioral Questions: Brief discussions about past experiences, teamwork, or problem-solving approaches.
