I appeared for an interview in Sep 2024, where I was asked the following questions.
Feature engineering is the process of selecting, modifying, or creating features to improve model performance.
Identifying relevant features: Selecting variables that have predictive power, e.g., using age and BMI in health-related models.
Creating new features: Combining existing features, like creating 'total income' from 'monthly salary' and 'annual bonus'.
Handling missing values: Imputing missing data using mean, med...

I applied via LinkedIn and was interviewed in May 2023. There were 2 interview rounds.
Outliers in a boxplot are defined as data points that fall below Q1 - 1.5*IQR or above Q3 + 1.5*IQR.
Calculate the interquartile range (IQR) by subtracting Q1 from Q3.
Identify the lower bound as Q1 - 1.5*IQR and the upper bound as Q3 + 1.5*IQR.
Any data points below the lower bound or above the upper bound are considered outliers.
For example, if Q1 = 10, Q3 = 20, and IQR = 5, then the lower bound = 10 - 1.5*5 = 2.5 and t

IQR stands for Interquartile Range, a measure of statistical dispersion.
IQR is calculated as the difference between the 75th percentile (Q3) and the 25th percentile (Q1) of a dataset.
It is used to identify the spread of the middle 50% of the data points in a dataset.
IQR is less sensitive to outliers compared to the range.
Formula: IQR = Q3 - Q1
Missing values can be filled using techniques like mean, median, mode imputation, or advanced methods like regression or machine learning algorithms.
Use mean, median, or mode imputation for numerical data
Use mode imputation for categorical data
Use regression or machine learning algorithms for more complex datasets
The duration of Technocolabs interview process can vary, but typically it takes about less than 2 weeks to complete.
