Pregunta 1
3 interviews were straight away scheduled.
Round1 with associate data scientist, round2 with senior data scientist and round 3 with director of data science.
Round 1- They asked me the following questions:
1. Input feature selection
2. Anomaly detection
3. Class bias problem
4. Categorical data in classification
5. How are weights being assigned internally
6. How categorical data in decision trees is handled
7. Random Forest, Gini Impurity, Entropy, Information Gain
8. Cost function
9. Why cost function used in place of differentiation
10. Bagging vs Boosting. Advantages/disadvantages of each.
11. Skipgram
12. Custom NER and case where you applied
13. Lemmatization
14. Stemming
Round 2:
1. Linear Regression and Logistic Regression
2. Maximum Likelihood
3. Bernoulli in logistic regression
4. Cost Function and cost function of logistic regression
5. Skipgram and CBOW
6. LSTM/BiLSTM
7. RCNN
8. Masked RCNN
9. AIC BIC scores
10. Random Forest
Round 2 majorly had questions from the resume. They have statisticians who are working as a data scientist. I was not able to answer or explain my answers so I knew my results already.
Still I went ahead and gave round 2 where the same fate repeated and I finally accepted that I won't be able to make it. The people taking the interviews leave no stone unturned to ask you questions in detail and in case you fail, you know the results just like I knew.
I am not waiting for the round 3 as I know I won't be selected. Still I am sharing the questions to help others.
Very conversational, easy going, focussed on relevant skills and no unnecessary filler questions. 3 focussed rounds and prompt replies from HR after every round. they were quick to catch up as well. friendly employees

Great process and help you thought the process. Give you immediate feedback and reasons as to why you may or may not be successful. Lots of study needed though. Overall good experience
