Why are you in consulting?
I have cleared the initial technical round for senior data scientist position at CVS health. I have 2-3 more rounds of interviews. I heard my next round is with sr manager data science to check team fit. Can anyone who went through the process please let me know what type of questions will be asked. Thanks in advance.CVS Health

It involves 2 python and 2 sql questions which needs to be solved in 120 mins. I was able to solve all pass all test cases except for 1 test case in last python question. Later got invited for final rounds
I am also doing a DE assessment, would love to learn more!
So I took the data science test and it was purely Python3 based. To be fair, I did not check the possibility to switch to other languages, it could be the case.
Structure is the following:
1. Algorithmic question (similar to the hackerrank practice questions in the algorithmic section)
2. Model
3. Model with more data
My recommendation is to manage your time well (2hrs in total) and get used to the hackerrank UI before you take the test. I wrote and tested my code in my preferred interpreter with dummy data and pasted the solution into the UI to run it against the test cases later. It also seemed that the code was evaluated by a person and not purely by passing/failing test cases.
Hi,
Congratulations on clearing this round!
I took the Hackerrank test 2 days ago for a Data scientist intern role. There were 2 python and 1 modeling question to solve in 120 mins. For the first python question, my server kept timing out may be because my code wasn't optimised due to lack of time and I could not run 3/15 test cases. I am sure the code wasn't wrong, but it could have been more efficient. For the rest everything worked well. Do you think I might hear back from them and if yes, what does the timeline look like?
Thank you so much!
Edit: I DMed D1 who took the coding test for Data Engineering.
Planning on taking the Data Science test soon. Will post an update.
Have you taken the test yet?
For those following the thread: I went through the technical screening. My advice: inform yourself on glassdoor about the questions asked in previous interviews. This covered 60-70% of my questions. Be prepared to know the concepts deeply and able to differentiate between methods and algorithms. I allowed myself to “spice in” some additional concepts where appropriate. For example, when asked about an algorithm I explained which limitations it has and how to solve it through e.g. data prep.
Yes

Hi, I am giving hackerrank test for data engineer next week.
Kindly suggest on what areas should I be prepared with.
hello, care to share what type of questions are asked?
Can someone Help me in the practice for the QB Data Science test, I need some clarity on the Algorithmic questions and type of modelling question(whether it would be a Time Series Problem, multiple Linear Regression or so on)?
