GS Lab interview Experience | Set 3
The first round was written round which was conducted by Hackerearth.
1st 5 questions were from aptitude, the 2nd section was from SQL queries, the 3rd section was from os and data structure and final section was 2 coding question.
1st coding question was very cool number
The 2nd coding question was a pattern.
1st technical round they asked me about my project which I had done using tableau and they said to me if I had to do it in SQL how can I visualize data, they said to me to do the Er model of the table, then some join query and told me to explain how does it happen
and then gave an instance how can I get information about a family from the table and how can I optimize by adding the new table.
Too many SQL queries.
NOTE: You have to Qualify each round to go to the next round.
They asked me about my next project which was based on home automation and real-life case scenario where it can be implemented.
Then questions about the operating system, more SQL, and advanced SQL and finally java questions.
