Coding Technical System Design Behavioral Case
So HashedIn by Deloitte came to our campus for SDE and SDET roles. I applied and my resume got shortlisted for the online assessment. It was a test with 3 coding questions: Easy, Medium, Hard. I managed to solve the Easy and Medium ones. For the Hard one, I passed most test cases but not all. After that, I was shortlisted for the interview rounds. On Day 2, we had the interviews. Round 1 was Technical, covering coding, database, and SQL. They asked questions on database design for a Facebook-like site with SQL queries, finding the 75th, 76th, and 77th lowest salaries, and coding problems like Minimum Window Substring and a String decoding problem. I did above average and moved to the next round. Round 2 was all about Database Design, focusing on system design and database concepts. The main task was to design a Movie Booking System, including the database schema, E-R Diagram, relationships, constraints, and optimizations. The interviewer went deep into my design, suggested improvements, asked SQL queries on my schema, discussed normalization, and drilled down on my internships and projects, reviewing my resume. No coding in this round. Round 3 was an HR Discussion with two panelists. They asked behavioral, situational, and company-related questions, assessing cultural fit and career goals. In the end, 10 students were selected from our campus: 8 for SDE and 2 for SDET.

Coding Technical
So basically, for HashedIn by Deloitte's campus hiring, the first round was an online test which was a coding round. It had 3 coding questions, mainly focused on DSA like strings, sliding window, and prefix sums. It was for 90 minutes on the HirePro platform. No MCQs, just DSA coding questions. They were kinda medium-hard difficulty, so you really need to know strings, sliding window, prefix-sum, and hashing well. HirePro doesn't give any partial scores, your code has to pass all the test cases. You could use Java, Python, or C++.

Coding Technical System Design Behavioral
This was a 4-stage interview process. It started with an online assessment that had 3 DSA questions: one easy, one medium, and one hard. You had to solve all three to move on. Then, there were two technical interviews. The first one involved 2 medium-to-hard DSA questions, a review of my resume, and some Computer Science fundamentals. The second technical interview was a 40-45 minute system design round, focusing on database design for a given problem. Finally, there was an HR interview where they asked basic HR questions and discussed my resume projects.
