Amazon Berlin, SDE1
I applied for amazon hiring event at Tokyo. I had a coding round followed by an half hour phone interview . I cleared both but the event was targeted for graduates., so the HR asked me if I am interested in interviewing for SDE role at Amazon Berlin. I agreed and then got scheduled for 3 back to back interviews of 1 hr each.
Coding round:
2 medium level questions
Half hour interview:
Few very basic technical questions like complexities of algorithms, BSTs etc, and Leadership priniciples.
Each of the 1 hour interview had half hour for leadership principles and next half for coding.
For the coding part, I was supposed to write the complete code on text editor. The questions were:
Round1
Merging 2 Binary search trees.
Round2
Given unsorted array of flight tickets(pair of source and destination place) . Output a list with cities in order they are visited. Eg [ [A,B] ,[C,D], [B,C]]. So clearly the only possible travel pattern would be A->B->C->D. Also there is "no" round trip.
Round3
A matrix was given with some cells having obstacles. Output path from given source to destination.
Also, they focused a lot on leadership priniciples and cross questioned a lot. So make sure you have stories prepared . And while writing the code, discuss the time and space complexities.
Behavioral questions
- Situation when you has multiple solutions to choose from but had a tight deadline so a quick decision had to be made.
- Sitaution when you helped your co-workers/friends.
- When you failed, what aspects would you change if got a chance again.
- where you worked out of your comfort zone
Few days back , I got the offer for the position. :)
For leadership principles Dan Croiter Videos on youtube are a must. Have at least 2 stories prepared for each question and practice them in STAR format. Many people dont realise the importance of leadership principle questions and fail.
For coding part leetcode consistent practice is enough. Have clear concepts and practice white board coding.
