Interview preparation journey

Journey

For this role, I focused more on core subjects instead of DSA. I only practised basic questions of DSA from GeeksForGeeks. I practised System Design, Networking, OOPs, DBMS from various youtube channels. I was also interested in Cloud computing, so I later took a course for the same.

Application story

This company visited our campus for the placement. First, we applied by filling the forms. They shortlisted on the basis of GPA. Later, they called us for the interview rounds.

Why selected/rejected for the role?

I was rejected because I think that the interview was focused around a wide variety of topics. I was not able to prepare all the topics in a depth manner. I just had knowledge of basic fundamentals.

This was the first round of elimination. The round consists of 7 sections.
1) Logical: It consisted of all the common aptitude questions.
2) Quantitative & Verbal: This section had around 20 questions overall. It consisted of five questions about data interpretation followed by 15 questions that tested the verbal ability.
3) The next section was purely based on the Markup language(HTML), CSS, and JavaScript. This section was very unexpected as this was the only company that had markup languages in the test. But they had clearly mentioned that they expect the candidates to have knowledge of HTML, CSS.
4) SQL: This section consisted of objective questions. We were given a schema and the required output(For Eg: Find all the employees whose manager is Mr. Rahul Soni). The answer had 4 options and we were expected to mark the most appropriate query.
5) Probability: This section was the most difficult question. It had sections revolving around Probability. I could not solve even a single question from this section and had to mark answers randomly.
6) Code Snippets: It tested the knowledge of C, Java with questions revolving around core concepts of the language. Geeks for Geeks is the best platform where you can practice such concepts.
7) Machine learning + Coding: The section consisted of 2 MCQs and a coding question. The time that was allotted for this section was 10 minutes. The solution to the coding question that I had got was very basic and it struck me very soon so I could do it in 8 minutes.
