Based on recent interview experiences, the programming round at Solverines Technology Solutions focuses on checking a candidate’s logical thinking, problem-solving ability, and coding approach. Instead of asking complex development projects, interviewers usually provide a problem statement and observe how the candidate analyzes the requirement, develops the logic, and writes the solution. Candidates who practice coding problems regularly are generally more comfortable handling this round.
Password Validation Program
A company wants to validate passwords before allowing users to create an account. Write a program to check whether a password satisfies the following conditions:
- ⭕ Minimum length should be 8 characters.
- ⭕ It should contain at least one uppercase letter.
- ⭕ It should contain at least one lowercase letter.
- ⭕ It should contain at least one digit.
- ⭕ It should contain at least one special character.
If all conditions are satisfied, display “Valid Password”. Otherwise, display “Invalid Password”.
Answer
password = input("Enter Password: ")
has_upper = False
has_lower = False
has_digit = False
has_special = False
for ch in password:
if ch.isupper():
has_upper = True
elif ch.islower():
has_lower = True
elif ch.isdigit():
has_digit = True
else:
has_special = True
if (
len(password) >= 8 and
has_upper and
has_lower and
has_digit and
has_special
):
print("Valid Password")
else:
print("Invalid Password")Explanation
This problem checks whether a candidate can work with loops, conditions, string processing, and validation logic. The interviewer is usually interested in understanding how the candidate verifies multiple rules within a single program.
Number Printing Programs
Write a program to print numbers from 1 to 100.
However:
- ⭕ Print “Prime” if the number is a prime number.
- ⭕ Print “Even” if the number is an even number but not prime.
- ⭕ Print “Odd” if the number is an odd number but not prime.
Answer
for num in range(1, 101):
is_prime = True
if num < 2:
is_prime = False
else:
for i in range(2, int(num ** 0.5) + 1):
if num % i == 0:
is_prime = False
break
if is_prime:
print("Prime")
elif num % 2 == 0:
print("Even")
else:
print("Odd")Explanation
This problem is more useful in interviews because it combines loops, conditions, mathematical logic, and decision-making in a single program. It allows interviewers to understand how candidates approach problem-solving instead of simply recalling a common coding pattern.
Logical Programming Questions
A warehouse contains N storage boxes arranged in a row.
Initially, every box is marked as Closed (0).
The supervisor performs multiple operations.
During each operation, all boxes between a given start position and end position are toggled:
- ⭕ Closed (0) becomes Open (1)
- ⭕ Open (1) becomes Closed (0)
After completing all operations, display the final state of every box.
Example
Input
Boxes = 7
Operations = 3
1 4
2 6
5 7Output
1 0 0 0 0 0 1
Answer
boxes = 7
states = [0] * boxes
operations = [
(1, 4),
(2, 6),
(5, 7)
]
for start, end in operations:
for index in range(start - 1, end):
if states[index] == 0:
states[index] = 1
else:
states[index] = 0
print(*states)Explanation
This problem evaluates a candidate’s ability to work with arrays, nested loops, indexing, and logical state changes. Interviewers often use similar problems because they reveal how a candidate approaches real-world logic implementation rather than memorized syntax.
