The interview Process consists of 4-5 rounds in total. The rounds are aptitude, first technical, second technical and HR round. Candidate must be good at coding because there are compulsory coding questions aptitude as well as technical rounds.
Questions d'entretien [1]
Question 1
1. Coding question.... Find the second largest number from the given list of numbers. ( We can do the coding in any interface we are comfortable in).
2. Explain about the Project that you have done.
3. Detailed Explanation about anyone Machine Learning Algorithm of your choice. ( Choose the one that you have clear understanding about because interviewer expects detailed explanation.
4. What are the steps involved while doing EDA?
5. What kind of correlation is used in EDA?
6. Few definitions in NLP like Lemmatizing, tokenizing and etc?
( Make sure you appear to the interview confidently and with a positive approach.)
I hope this helps.
