While working in TCS, she wanted to explore the latest technologies and the perfect one she found was Hadoop. After giving it a thought, Shuchi made the final decision to go ahead with Big Data and Hadoop. She searched a lot, then found the reviews of DataFlair. Hear it from Shuchi  - 

When I was working in TCS, I felt a need to update myself with the new cutting-edge technologies. I had set my mind to Hadoop and Spark. I inquired, searched a lot for the institutions who provided the best training. One day while searching I found DataFlair, read all the facilities and features which they provided, read previous students reviews, and asked them about the course. After all this, I was satisfied and finally enrolled for Big Data Hadoop and Spark Course . That was the best decision of my life.

How did DataFlair help her grow in Big Data?

At DataFlair, Shuchi got the practice material, project ideas, and mock interview sessions which built her confidence enough to let her face any Big Data interviews. Let's see Shuchi's opinion for this -

Mostly the training sessions at DataFlair were scheduled for the weekend so that each had the time to learn. Along with the live sessions, they provided me with videos and practice material. Also, they prepared me for interviews through their mock interview sessions. Whenever I faced any hurdles, the instructor was there for help. Not only this, he always encouraged the students for practicing a lot. These preparations proved helpful for me when I faced the Infosys interview. Without practice, I couldn't have cracked the interview. Thanks to the DataFlair Team.

Shuchi's Interview Experience

I would love to share my Infosys interview experience with all of you. Hope this will help others.

So, there were total 3 rounds - 2 Technical and 1 HR. The first technical round went for about 50 minutes and the second was for 30 minutes. Basically, they covered the topics mentioned in my resume such as MapReduce, HDFS, Hive, Flume, Spark, Sqoop.
