Interviewer Expectations for this Question
01
Core Competency
Assesses fundamental understanding of Python conventions, runtime behavior, and memory/performance considerations.
02
Evaluation Criteria
Hiring managers look for precision, avoidance of ambiguous jargon, and ability to explain trade-offs under real production conditions.
Comprehensive Model Answer
Verified Solution
# Displaying Fibonacci sequence
n = 10
# first two terms
n0 = 0
n1 = 1
#Count
x = 0
# check if the number of terms is valid
if n <= 0:
print("Enter positive integer")
elif n == 1:
print("Numbers in Fibonacci sequence upto",n,":")
print(n0)
else:
print("Numbers in Fibonacci sequence upto",n,":")
while x < n:
print(n0,end=', ')
nth = n0 + n1
n0 = n1
n1 = nth
x += 1
Output:
1
0, 1, 1, 2, 3, 5, 8, 13, 21, 34,
Candidate Response Strategy & Interview Tips
- Start with a concise one-sentence summary: Deliver a direct, confident answer first before expanding into nuances.
- Demonstrate real-world trade-offs: Discuss where this approach excels and when you would avoid it in production systems.
- Discuss complexity & edge cases: Proactively explain time/space complexity or boundary conditions (null values, scale limits).
- Prepare for interviewer follow-ups: Technical hiring panels frequently probe deeper into concurrency, backward compatibility, or alternative libraries.
