SQL JOIN functions combine rows from two or more tables based on related columns.
INNER JOIN: Returns records with matching values in both tables. Example: SELECT * FROM A INNER JOIN B ON A.id = B.id;
LEFT JOIN: Returns all records from the left table and matched records from the right table. Example: SELECT * FROM A LEFT JOIN B ON A.id = B.id;
RIGHT JOIN: Returns all records from the right table and matched records ...
Mean, median, and mode are measures of central tendency used to summarize data sets.
Mean: The average of a data set, calculated by summing all values and dividing by the count. Example: For {2, 3, 5}, Mean = (2+3+5)/3 = 3.33.
Median: The middle value when data is sorted. If even number of values, it's the average of the two middle numbers. Example: For {1, 3, 3, 6, 7}, Median = 3.
Mode: The value that appears most f...
Multicollinearity occurs when independent variables in a regression model are highly correlated, affecting model reliability.
Multicollinearity can inflate the variance of coefficient estimates, making them unstable.
It can lead to misleading statistical significance of predictors.
Example: In a model predicting house prices, including both 'square footage' and 'number of rooms' may cause multicollinearity.
Detection ...
Variance Inflation Factor (VIF) quantifies multicollinearity in regression models, indicating how much variance is inflated due to predictors.
VIF measures how much the variance of a regression coefficient is increased due to multicollinearity.
A VIF value of 1 indicates no correlation among predictors, while values above 5-10 suggest high multicollinearity.
For example, if a predictor has a VIF of 15, it indicates t...
Behavioral questions assess how past experiences shape your work style and problem-solving abilities.
Describe a challenging project: Led a team to deliver a complex software solution under tight deadlines, improving efficiency by 30%.
Conflict resolution: Mediated a disagreement between team members, fostering collaboration and resulting in a successful project outcome.
Adaptability: Transitioned from a monolithic a...
The 3 Sum problem involves finding triplets in an array that sum to zero.
Sort the array to simplify finding triplets. Example: [-1, 0, 1, 2, -1, -4] becomes [-4, -1, -1, 0, 1, 2].
Use a loop to fix one element and apply two-pointer technique for the remaining elements.
Skip duplicates to avoid repeated triplets in the result. Example: For [-1, -1, 0, 1], only consider unique combinations.
To print nodes with no edges in a unidirectional graph, iterate through all nodes and print those without any outgoing edges.
Iterate through all nodes in the graph
For each node, check if it has any outgoing edges
If a node has no outgoing edges, print it
A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers.
A prime number has exactly two distinct positive divisors: 1 and itself.
Examples of prime numbers include 2, 3, 5, 7, 11, and 13.
The number 1 is not considered a prime number.
The only even prime number is 2; all other even numbers can be divided by 2.
Black box testing is a software testing method where the internal structure or code of the application is not known to the tester.
Tester focuses on the functionality of the software without knowing its internal workings
Tests are based on requirements and specifications
Input data is provided and output is compared against expected results
Examples include equivalence partitioning, boundary value analysis, and decisi...
Regression testing is the process of retesting a software application to ensure that new code changes have not adversely affected existing functionality.
Regression testing is performed after code changes to verify that the existing features still work correctly.
It helps in identifying any defects introduced by new code changes.
Automated testing tools are often used for regression testing to save time and effort.

I appeared for an interview in Jun 2025, where I was asked the following questions.
- Q1. What is multicollinearity, and how can it be prevented?
- Ans.
Multicollinearity occurs when independent variables in a regression model are highly correlated, affecting model reliability.
Multicollinearity can inflate the variance of coefficient estimates, making them unstable.
It can lead to misleading statistical significance of predictors.
Example: In a model predicting house prices, including both 'square footage' and 'number of rooms' may cause multicollinearity.

- Ans.
Variance Inflation Factor (VIF) quantifies multicollinearity in regression models, indicating how much variance is inflated due to predictors.
VIF measures how much the variance of a regression coefficient is increased due to multicollinearity.
A VIF value of 1 indicates no correlation among predictors, while values above 5-10 suggest high multicollinearity.
