PracHub editorial advice for the preparation topics above.
Going into the loop without having done this.
To stand out in your interviews, keep these practical tips in mind:
Going into the loop without having done this.
Showcase your passion: Our interviewers love to see candidates who are genuinely excited about technology and its real-world applications. Be ready to talk about past projects, technical challenges you've overcome, or modern technologies you enjoy working with.
Going into the loop without having done this.
When discussing past projects, use the STAR method (Situation, Task, Action, Result) to structure your answers. Be sure to highlight your specific contributions and the measurable impact of your work on the business or team.
Going into the loop without having done this.
Focus on clean code and communication: During coding sessions, don't just jump into writing code. First, clarify the requirements, talk through your planned approach, discuss any trade-offs, and then write clean, well-structured code.
Choose a category, try a prompt, then open its approach, worked solution or follow-up when you need it.

Write a function to reverse a linked list, both iteratively and recursively, and explain the space-time complexity of each approach.
Approach
- Restate the input: its shape, its size, and what is guaranteed about it.
- Name the brute-force solution and its complexity before improving on it.
- Choose the data structure from the access pattern, not from familiarity.
- State the target complexity and say which constraint rules the naive version out.
Follow-up
- How does this change if the input no longer fits in memory?
- What is the worst case, and how likely is it on real data?
