How I became Big Data Architect?
You must be wondering about my strategies and preparation to learn and crack the interview. But before that I want you to make aware of my background.
I was a Civil Engineer. Yes, you read correctly. After civil engineering, I was a system analyst and was working with BI technologies for about 12-13 years. Then my life changed, I became a Big Data architect from a non-programmer system analyst.
What motivated me to make a career switch in Big Data?
I was not enjoying my work and also had a fear of slow career growth. This is something that helped me to make a career switch.
Spending more than half of your daily time at your workplace and that too with fear of losing a job. If this is the case with you then you also need to make a move right now.
Why only Big Data?
Many friends asked the same question. The one-line answer is - "Big Data is the Future".
Like others, I also wanted a secured and growing career for myself. When I felt a need to change my career, I started to research.
At the office, I was working on BI technologies and at home, I was preparing a plan for my career. I explored a lot of researches, surveys and what I found was Big Data.
Big Data is everywhere. And with the help of online available surveys, I got to know that this is one of the technologies which will last for decades. What else one needs.
From that moment, Big Data became the only choice for me. But being a non-programmer, I was afraid. Many questions were there in my mind. The first one was - “How To Learn Big Data”
How did I learn the concepts of Big Data?
Now, here I am sharing the secret of my Big Data journey.
As I already researched a lot about big data, so, at this point, I was aware of the technology and its use. So, my next step was searching for a mentor/trainer.
I started exploring for Big Data online training. The perfect one I found was DataFlair and trust me that was the best decision of my life. I immediately enrolled for the Big Data, Hadoop, Spark, and Scala Course. And my learning started.
I got the best trainer. He always used to explain the topics with real-life example and that helped me a lot. DataFlair provided me practicals, assignments, real-time projects and most importantly the doubt clearing sessions.
When I learned the concepts of Big Data, I attended Mock Interview Sessions. Mock interviews are the best part of online courses. You can test yourself and prepare accordingly. I did the same.
This is how I learned Big Data and gain the confidence to face the interview. A big credit goes to DataFlair.
How did I face the Interview?
Again DataFlair’s Learning Management System helped me in this. I went through LMS for almost 4 times. Trust me you can clear 90% of the technical rounds through this only.
Along with this, mock interviews and discussion forums were very helpful.
I faced 4 rounds - 3 Technical Interview Rounds and 1 HR Round.
Some of the questions asked to me during the interview -
Q.1 What is the data flow and which technologies you used?
Q.2 Why did you use big data technologies in your project?
Q.3 How to improve the performance in HIve query/view?
Q.4 Explain about your Scala and Spark Project.
Q.5 What is Currying?
Q.6 What is Higher Order Function and why do we need it?
Q.7 Explain Singleton in Scala.
Trust your trainer and follow her instructions sincerely, the only way to achieve success in your career.
So, this is how I became a big data architect. I hope you got the answers to all your questions related to the big data career.
