I applied through college or university. The process took 2 months.

AMAZON SDE INTERN EXPERIENCE Sharing my Amazon SDE Intern on-campus interview experience. For our campus drive, only candidates who opted for Bangalore location were shortlisted for OA.

Selection Flow:

• 37 students were shortlisted for OA
• 7 students were shortlisted for Round 1
• 3 students were shortlisted for Round 2
• No one got job offer

OA Pattern:

• Frequency-based sorting question (sort bug IDs based on frequency ascending, if same frequency smaller ID gets priority)
• Array transformation + minimum cost problem (greedy + observation based)

Apart from coding, OA also had:

• Work Simulation Assessment (Amazon Leadership Principles based situations)
• Feedback/workstyle survey

Round 1: It was a 1-hour virtual interview with Zoom + live coding platform. The interviewer first introduced himself and then asked me for a quick self intro. After that he asked: “What language are you comfortable with?” I chose C++. He expected:

• brute force first
• optimized solution
• complexity explanation
• dry run after coding

DSA Questions:

• Q1: Shortest path in grid with obstacles
  • Follow-ups: Why BFS not DFS? Complexity? How to avoid cycles?
• Q2: Modified version of first question: minimum walls to break
  • Follow-ups: Which data structure is suitable? Can nodes revisit, if yes how may times? Edge cases

Since I mentioned RAG/GenAI projects in intro, interviewer also asked:

• Explain RAG
• Hallucination verification
• How would you semantically search huge log files with millions of lines and how do you optimize it?

Discussion involved: chunking, embeddings, vector DB, scaling.

Round 2: It was also a 1-hour virtual interview and was more behavioral + problem solving focused. Initially both interviewers introduced themselves and then asked me for a self introduction. Behavioral questions were mainly based on Amazon Leadership Principles.

• Tell me about a situation where a teammate had a different thought process
• What problem did you solve in JPMC Code for Good?
• Explain a time when you had to deliver something important under deadline pressure
• What sacrifices/tradeoffs did you make to meet the deadline
• What was the final impact/outcome?
• Tech stack used in mentioned project and how you handled implementation challenges

Since time was ending, they asked only 1 DSA question in my Round 2.

Coding Question:

• Next warmer temperature in a circular array. Example: temps = [73,74,76,71] Output: [74,76,-1,73]

Overall observation: Different panels followed different patterns. Some people got:

• more behavioral/Amazon Principles questions
• only 1 DSA
• more GenAI discussion

It mainly depended on time and interviewer style. One important thing, they focused a lot on:

• communication
• explaining thought process
• handling follow-up questions and reasoning under pressure

Not just final answers.
