Getting a break in the field of data science comes with a lot of challenges as one needs to learn and memorize a lot of complicated concepts and become skilled in applying them in real-world situations. Are you an aspiring data scientist who is struggling to crack interviews? You are not alone! Many aspiring data scientists have faced a lot of challenges in the process of bagging their very first machine learning job as a beginner. So, it is always better to be highly prepared before facing a machine learning interview.
How will the structure of a machine learning interview be? How must my body language be? What are the most common questions that will be asked? What are the specific areas of machine learning that I must prepare for? What resources should I refer to? These are some of the common questions candidates will be plagued with before attending a machine learning interview. In this article, we will share a list of areas that every aspiring machine learning interview candidate must prepare for in order to crack a machine learning job interview.
Let us start by understanding the term ‘machine learning.’
What is Machine Learning?
Machine learning refers to machines being able to learn by themselves without being explicitly programmed. It is an application of AI which enables systems to learn and improve from experience automatically. While working with machine learning, various sets of algorithms are required. These algorithms use a set of training data to enable computers to learn. Machine learning is a subset of artificial intelligence.
Interview Tips For Beginners
Here, we will list down some useful tips and tricks that will guide you through your machine learning interview process and help you come out in flying colors. The areas one needs to be familiar in are:
1. Data Science and Statistics Questions
This section will test, improve, and enhance your data science and statistics concepts. Right from probability to coding to correlation, linear regression to logistic regression, and SQL to data analysis. Learning these concepts will help you give a tough fight in your job interview. These concepts will help you gain a clear understanding of machine learning and related statistical concepts.
2. Machine Learning Questions
Machine learning has become crucial to the strategies of a lot of organizations. Going through many machine learning questions and learning the right answers will help you test your machine learning skills to know where you stand in the interview. If you are one looking to carve a niche for yourself in this field, you must be prepared to face hard and difficult questions that involve mastering a lot of concepts. As soon as you start aspiring to be a data scientist, you must start gaining a conceptual knowledge of machine learning and make yourself industry-ready. There are no two ways about it.
3. Deep Learning Questions
This is currently the hottest research field in the industry. It is leading to amazing discoveries, incredible breakthroughs, and awesome innovations. If you manage to land a job interview, you must make sure that you are completely prepared for the hard questions. It is very important for you to remember that there is no easy way out while working in the deep learning domain. You must be familiar with concepts like logistic regression, image processing, image data, cross entropy, and gradient descent, to name a few.
4. Puzzles and Guess Estimates
If you are aspiring to have a successful career in the machine learning domain, the ability to quickly calculate and structure thoughts is critical. It really pays to be an out-of-the-box thinker. These are exactly the first things interviewers will test you on. In interviews, you will be given a puzzle or guess estimate questions to check how quickly and logically, you are able to solve a challenging problem. Guess estimate questions are a common part of analytics and management consulting interviews. Always remember that some of the most tricky questions can have the simplest of solutions.
5. Tool or Language-Specific Questions
Every individual aspiring to make it big in the machine learning field must have mastered at least one tool to produce quality analysis. But there is no need for you to limit yourself to one. If you can master more than two or three, it will make a great impression in interviews, because the more tools you know, the more diverse your skillset will become. This will increase your chances of landing the preferred job. This will require you to master the frequently asked questions in interviews regarding the tools such as Python, R, SQL, SAS, Excel, MATLAB, Apache Spark, BigML, and Tableau. You must have a fair idea of some of these tools before you face the interview panel as questions on these tools are a mandatory part of every machine learning interview.
Conclusion
Getting that first big break in analytics is a dream and is very critical for every candidate who aspires to have a successful career in the machine learning domain. Learning and mastering the concepts and question areas mentioned in this article will, no doubt, help you get picked by organizations and land in the most lucrative jobs in the field of data science. Gear up to face the interview process and crack the job interview by mastering these concepts.
