Seattledataguy

 
Seattledataguy has put together a data science study guide to help people prepare for their interviews. The excel sheet: Data Science Interview Guide was created by people who have been interviewed by big companies such as Amazon, Facebook, and more. 

If you would like to use the sheet, you can make a copy and follow the study guide whilst adding in your personal notes. 

Topics include:

  • Machine Learning Algorithms
  • Probability And Statistics
  • Product And Experiment Designs
  • Programming
  • SQL

 Cheat Sheets

 

Cheat Sheets are a great way to learn complex topics in layman’s terms. Instead of me jotting down every cheat sheet out there, have a read of this article by Abid Ali Awan (@1abidaliawan) who published two articles on KDnuggets. You will be able to find every cheat sheet you need for learning Data Science and preparing for your interview. 

  1. The Complete Collection of Data Science Cheat Sheets – Part 1
  2. The Complete Collection of Data Science Cheat Sheets – Part 2

The above resources provided will help you get the best results out of your Data Science Interview. However, there are a few things you can do for yourself to make the process easier. 

 

 Research the role and company

 

Learning more about the role and the company you have applied for will help you a lot. Make sure you understand what the role is asking of you and if you fit that specification. It is better to over-perform than underperform. 

If there are particular tasks laid out on the job description that you are unfamiliar with or need some brushing up on, you can use the time before your interview to prepare for that. 

Doing additional research on the company and its goals will impress the interviewer, as it shows you are eager to learn more about them. 

 

 Strengths and Weaknesses

 

Understanding your strengths and weakness in your soft and hard skills will give you a better guide on what you need to improve on. Being honest with how good your technical skills are upfront about the skills you don’t have will give the interviewer a better understanding of where you can benefit the company. 

Saying yes to every skill will only put you in the deep end when you get the job and you’re asked to do a particular task that you have no experience in. Selling yourself is important, however, lying doesn’t help the process. 

If you don’t have a particular skill they are looking for but later on get offered a second interview, use that time to impress them by learning more about that skill.

 

 Ask questions

 

Interviewers like people who ask questions. It allows them to interact with you more, teach you about their company and learn the kind of person you are. 

These questions can be about the role you are interviewing for. Is it a replacement role? Will training be provided? What would my typical workday look like? How many people are there on the team? Who will I be working closely with? What kind of candidate is the company looking for?

You can also ask more personal questions such as: what do you like about the company? What do you think the company could improve? 

All these questions give both the interviewer and interviewee a better understanding of one another and if they are the right person for the role. There is no harm in asking questions, so ask away!

 

Conclusion

 

I hope Part 1 and Part 2 of this Data Science Interview Guide have been helpful. I wish you all the best in your Interview and hope you land the job that you want!
