Tonbo Imaging hiring process
1. Application and resume screening
Candidates apply through Tonbo's careers page, job portals, or referrals. Recruiters shortlist resumes based on hardware, electronics, optics, or software skills relevant to the specific role.
2. Online or written technical test
Shortlisted candidates typically take a technical test covering core electronics, optics, or programming fundamentals depending on the role applied for. This step usually filters candidates before technical interviews begin.
3. Technical interview round 1
A technical panel evaluates domain knowledge in imaging systems, embedded electronics, or software, along with problem-solving on real engineering scenarios. Past academic or industry project work is discussed in depth.
4. Technical interview round 2
A second, deeper technical round covers system-level design, hands-on hardware experience, and scenario-based questions on defence-grade reliability requirements. Candidates may be asked to reason through failure scenarios in the field.
5. Managerial round
A hiring manager assesses ownership of past projects, precision in technical work, and fit with Tonbo's mission-critical engineering culture. Confidentiality and attention to detail are commonly emphasised.
6. HR discussion and offer
The HR team discusses compensation, security clearance requirements where applicable, joining timelines, and shares the offer once all rounds are cleared. Background verification is typically thorough given the defence sector.
