Work Experience: 1 year as Software Engineer in a Sevice Based Company

Location: Hyderabad, India
Date: 1st May, 2020
Interview Process:
Round 1: Online Coding Assessment
- a coding challenge with two questions (90 min)
- Describe your approach section to discuss your coding solutions(15 min)
Each of the below round started with "Introduce yourself and tell about your current work" and for each coding question time complexity was discussed.
Round 2: DS & Algo- 24th April, 2020 (1 hour)
- Course Schedule
- Code for both DFS and BFS approach. Time Complexity and approach comparison.
Round 3: DS & Algo- 24th April, 2020 (1 hour)
- Find first occurence of any number in sorted array
- Find nth occurence of any number in sorted array
- Find count of any number in sorted array - Was told to write code for this question.
- Path Sum
Round 4: Bar Raiser- 29th April, 2020 (1 hour)
- Why Amazon?
- Maximum Sliding Window
- If you want to find median from a list or a stream which DS would you use and why?
- Few other questions on DS were asked like which DS to use when you want to get the last entered element.
Round 5: Hiring Manager Round- 29th April, 2020 (1 hour 15 minutes)
In this round mostly Leadership Principles were evaluated and one technical question was asked.
- Situation where you couldn't give timely deliverable given by mangager or client. How did you handle it?
- Situation where you got a chance to work with a completely new technology.
- Something that you did on your own without seniors telling you anything and it's impact.
- Situation where you received feedback from seniors or managers or client. How did you improvise?
- Situation when some of your teammate's work was effecting your deliverable. How did you tackle that?
- N-ary tree question where you have to pass information from root node to all other nodes. In one iteration information can be passed to one child at a time.
- How many minimum iterations are needed? What traversal(Inorder, Preorder, Postorder) would you use and which algorithm(BFS or DFS)?
Because of Covid-19 situation all the interviews were taken virtually(video conferencing) on Chime. All the interviewers were very friendly. Time Complexity is an important aspect for each question. I was told to write code as close to production as possible so make sure you handle all the edge cases. Overall I had an amazing experience.
After 2 days of the last round I got a mail for selection.
