Sopra Steria Senior Software Engineer Interview Questions and Answers

Q1. Explain center limit theorm
Ans. 
The center limit theorem states that the sum or average of a large number of independent and identically distributed random variables will tend towards a normal distribution.
• The theorem applies to a wide range of distributions, not just normal distributions.

• It is often used in statistical analysis to estimate population parameters.

• The theorem assumes that the random variables are independent and identically distributed...read more

Q2. Difference between covariance and correlation
Ans. 
Covariance measures how two variables vary together, while correlation measures the strength of their linear relationship.
• Covariance can be positive, negative, or zero, indicating the direction of the relationship between the variables.

• Correlation ranges from -1 to 1, with 0 indicating no linear relationship and -1 or 1 indicating a perfect negative or positive linear relationship, respectively.

• Covariance is affected b...read more

• It learns to predict the context of a word by training on a large corpus of text.

• The output of the hidden layer is used as the word embedding.

• There are two approaches to word2vec: continuous bag of words (CBOW) and skip-gram.

• CBOW predicts a word given it...read more

Q3. If client ask you improve the performance of the model without changing architect and data what will be your first step
Ans. 
Optimize model performance through hyperparameter tuning and efficient resource utilization.
• 1. Hyperparameter Tuning: Adjust parameters like learning rate, batch size, and regularization to enhance model performance.

• 2. Model Pruning: Remove unnecessary weights or neurons to reduce complexity and improve inference speed.

• 3. Quantization: Convert model weights to lower precision (e.g., from float32 to int8) to speed up co...read more
