Unbox Robotics

1. Preliminary Screening (HR/Talent Acquisition) A 15–20 minute call to verify your background. Focus: They will ask about your graduation timeline (relevant as you're final year), your experience with microcontrollers (ESP32/Arduino), and your interest in robotics. Tip: Mention your work on the multi-modal educational ecosystem and the smart attendance system. These show you understand "system-level" integration. 2. Technical Assessment (Online or Take-Home) Depending on the role (Embedded vs. Fullstack), you might receive: For Embedded: A task involving writing a driver or a state machine logic for a sensor (like the MPU6050 you’ve already used) or a small C++ coding test focusing on Data Structures and Algorithms (DSA). For Fullstack: A mini-project to build a dashboard that displays real-time "robot" data (perfect for your MERN skills). 3. Technical Round 1: Deep Dive into Fundamentals This is where they test your "Knowledge Debt." Embedded Focus: Expect questions on RTOS (FreeRTOS is common for ESP32), Communication Protocols (I2C, SPI, UART, CAN), and Interrupt Latency. They might ask you to explain how you’d optimize power for a battery-powered tool like your ESP32-C6 hacking project. Software Focus: Basics of Node.js event loops, MongoDB indexing, and React hooks. 4. Technical Round 2: System Design & Logic This round focuses on how you think about complex problems. Robotics Logic: They may ask you to design a simple gait control logic or explain how a swarm of robots avoids collisions (relevant to their "UnboxSort" system). Vibe Coding Check: If you used AI for your projects, they will likely ask you to manually dry-run a specific part of the code. They want to see if you understand the why behind the what. 5. Culture Fit / Founder Round Usually with a Senior Lead or occasionally a co-founder (Pramod or Shahid) for intern/fresher roles. Focus: Your ability to learn fast, your "vibe" (curiosity and ownership), and how you handle failures in hardware (e.g., "What do you do when the sensor gives garbage values?"). Strategy for your "Vibe Coding" background Since you’ve used AI to accelerate your development but need to master the underlying logic for interviews, try this "Logic Briefing" method: Audit Your Projects: Take your ESP32-C6 project and the MERN app. For every major function, write down a 2-sentence explanation of why it works that way. Example: "I used an interrupt for the RFID scan instead of polling to save CPU cycles for the Wi-Fi stack." Focus on the "Handshake": Unbox Robotics cares about how hardware talks to software. Be ready to explain how your handheld controller sends data to the MERN backend (WebSockets vs. MQTT). Hardware Troubleshooting: Be prepared to talk about logic analyzers or oscilloscopes. For an ECE student, knowing how to debug a physical signal is a major plus.

Round 1: Phone Interview – Initial screening round conducted over a phone call. Round 2: Panel Interview – A detailed technical and behavioural discussion with multiple interviewers. Round 3: Candidate Assessment (Startup Evaluator) – The Evaluation done by an external startup-based candidate analyser to assess overall fit and potential. Post-Interview – Did not receive any feedback, update, or response after completing all rounds.

One tech round and that's it. Also, might ask for some deliverables. To see your approach to the problem. The management seems off though because I wasn't informed of delays in my hiring process.

Looney company Numpty employees Lamebrained interview process Applied on January 2023, after that pin drop silence. One morning receive a call. Explained nothing about the company and told you have received a take home test (project) which you need to submit in two days. > le me "There goes my weekend." Project title: Create a whole system in which a server which produces a serialised speed value data stream. Consume the data in a front end system which will show the values. Also after two days there will be a interview based on the project. No information what architecture to choose, how to generate the data, how to send the data, how to consume the data. > Works my butt off to create something which works to my best understanding > Finally, my system works > Happy thinks it will be great as a showcase in interviews > The day comes I hop on the call > Explains everything to the interviewer > Looks at me strange!!! > Says. "Not impressed but good try" > I am like bro I don't know a lot the things, if project details were clear I would have done better. > after 30 mins calls end > next 40 min I receive a rejection email FML

it consist of two technical round and one HR round and one face to face round (HR + Technical). They ask basic questions related to SCM, SAP , purchase and store. They also seeking for candidate who has excellent knowledge of mechanical engineering with almost all manufacturing process and AI + Robotics basics.
