Experience:

Shashwat Mahale, an Electrical and Electronics Engineering student from NIT Warangal, was offered the role of Engineer – R&D at Sedemac. The selection process comprised multiple online tests and interview rounds.

Round 1: Aptitude Test: This round was 100 minutes long and included Qualitative, Quantitative, Verbal reasoning, and some Language questions.

Round 2: Technical Test (R&D Profile): This was a 2-hour online test. The questions were presented as paragraphs followed by multiple questions based on them. They focused on applying basic physics concepts, often similar across different engineering branches. The candidate found working on projects helpful for this round.

Round 3: Technical Interview (Level 1): This round started with the candidate's introduction.

• Detailed discussion on the candidate's hardware project, focusing on its limitations and potential solutions.
• Questions based on a given speed-torque curve of a fan.
• Divisibility test for 3 and its proof.
• Discrete probability distribution plot and how to obtain random numbers satisfying it.
• RC circuit questions.
• Question: "Can the sum of two irrational numbers be rational?" and other unconventional questions.

Round 3: Technical Interview (Level 2): This round involved:

• Writing pseudocode for a system that transitions between fail-safe and normal states based on temperature sensor signals. This was related to test automation, though prior knowledge of NI-LabVIEW was not required.
• A question about an infinite capacitor network.

Round 4: HR Interaction: The HR round was a simple discussion where the HR person introduced herself. The candidate discussed their previous internship and team working experience, along with relocation and compensation details. The candidate also provided feedback on the recruitment process.

Overall Experience: The preparation required brushing up on very basic concepts from 11th and 12th standards in electrical, electronics, and mechanical fields. The technical test was of "fine quality," assessing the ability to apply basic concepts to new situations. The candidate's projects and practice in self-introduction were beneficial.
