Interview Questionnaire 

4 Questions

  • Q1. 1. How to choose optimum probability threshold from ROC?
  • Ans. 

    To choose optimum probability threshold from ROC, we need to balance between sensitivity and specificity.

    • Choose the threshold that maximizes the sum of sensitivity and specificity

    • Use Youden's J statistic to find the optimal threshold

    • Consider the cost of false positives and false negatives

    • Use cross-validation to evaluate the performance of different thresholds

  • Answered by AI
  • Q2. 2. How to test time series trend break up?
  • Ans. 

    To test time series trend break up, statistical tests like Augmented Dickey-Fuller test can be used.

    • Augmented Dickey-Fuller test can be used to check if a time series is stationary or not.

    • If the time series is not stationary, we can use differencing to make it stationary.

    • After differencing, we can again perform the Augmented Dickey-Fuller test to check for stationarity.

    • If there is a significant change in the mean or va...

  • Q2. What is precision and recall
  • Ans. 

    Precision and recall are two important metrics used to evaluate the performance of a classification model.

    • Precision measures the proportion of true positives among all the predicted positives.

    • Recall measures the proportion of true positives among all the actual positives.

    • Precision and recall are inversely related and a trade-off exists between them.

    • A high precision means that the model is good at predicting positive ca...

  • Q3. What is regularisation
  • Ans. 

    Regularisation is a technique used in machine learning to prevent overfitting by adding a penalty term to the loss function.

    • Regularisation helps to control the complexity of a model and reduce the impact of irrelevant features.

    • It adds a penalty term to the loss function, which encourages the model to have smaller weights.

    • There are different types of regularisation techniques such as L1 (Lasso) and L2 (Ridge) regularisa...

Experience: Questions from all CS subjects including coding
Tips: They shortlisted 29 students for the final interviews on Day 1 Slot 1.
There were 2 rounds of technical interview and 1 interview.

General Tips: Do’s
1)      Start right from August 
2)      Prepare basics of subjects
3)      Try to code using pen and paper
4)      Code as many problems as you can from all domains with only 1 language (C/C++/Java)
5)      Keep a friend with you at all times during interviews. If you are selected for more than 1 companies in 1 slot, ask your friend to manage your interview schedules given he knows your priorities. I was not in a position to attend more than 2 interviews in the same slot.
Don’ts
1)      Don’t lose hope if you are not shortlisted for your dream company or any company of your choice because being an IITian you have large number of better choices and which would fit in your profile better.
2)      Don’t argue with the interviewers and never pretend that your are over smart in a given domain.
3)      Do not take HR rounds lightly even if you are sitting for CS companies.
