How Software Interviews Work
Understanding the pipeline helps you prepare for the right things at the right time.
Typical stages
| Stage | What happens | What it tests |
|---|---|---|
| Resume screen | A recruiter or system filters applications | Relevant projects, skills, clarity |
| Online assessment | Timed coding (and sometimes MCQs) on a platform | Problem solving under time pressure |
| Phone / video screen | 30 to 45 minutes with an engineer | One or two coding problems, communication |
| Technical rounds | 2 to 5 interviews, often in one day | DSA, CS fundamentals, projects, design |
| Behavioural / HR | Conversation with a manager or HR | Teamwork, motivation, culture fit |
| Offer | Compensation, team match, background check | Negotiation |
What interviewers look for
- Problem solving: can you break down an unfamiliar problem?
- Communication: do you explain your thinking clearly?
- Code quality: readable, correct, tested code.
- Fundamentals: data structures, complexity, OS, DBMS, networks.
- Collaboration: how you take hints and feedback.
Entry-level vs experienced
| New graduate | Experienced | |
|---|---|---|
| Coding | Heavy emphasis | Still important |
| System design | Light or none | Major round |
| Projects | Key differentiator | Impact and ownership |
| Behavioural | Basic | Leadership, conflict, scale |
An 8-week sprint plan
| Week | Focus |
|---|---|
| 1-2 | Revise arrays, strings, hashing, two pointers, sliding window |
| 3-4 | Linked lists, stacks, queues, trees, recursion |
| 5 | Graphs, heaps, dynamic programming basics |
| 6 | OS, DBMS, networks, OOP revision |
| 7 | Mock interviews, behavioural stories, resume polish |
| 8 | Light practice, rest, company-specific research |
TIP
Apply to many places and treat early interviews as practice. You improve fastest by interviewing, not only by studying.
