Interview format

4 rounds total.

System Design60 min

Design an analog/mixed-signal system, embedded processing platform, or industrial control system. TI interviews emphasize practical circuit and system-level thinking.

Coding / Firmware45 min

Firmware or embedded programming problem — may involve real-time scheduling, peripheral driver development, or DSP algorithm implementation.

Domain Technical45 min

Deep dive into analog circuit design, power management, embedded processors, or application-specific expertise (automotive, industrial, personal electronics).

Behavioral / Values45 min

Discussion about TI's values: integrity, innovation, and commitment. Assesses teamwork, customer focus, and long-term career alignment.

Commonly asked systems

Design a multi-output power management IC for a battery-powered deviceDesign a motor control system using a real-time microcontrollerDesign a data acquisition system with high-precision ADC and signal conditioningDesign a wireless sensor network for industrial monitoringDesign a battery management system for an electric vehicleDesign an audio codec with DAC, ADC, and digital filteringDesign an embedded processing platform for real-time industrial control

What they evaluate

Analog/Mixed-Signal KnowledgeHigh

Do you understand analog circuit fundamentals — op-amps, ADCs, DACs, voltage regulators, and signal conditioning? TI's core business is analog semiconductors.

Embedded Systems ProficiencyHigh

Can you design firmware for microcontrollers with real-time constraints, peripheral management, and low-power operation?

Application UnderstandingMedium-High

Do you understand how semiconductors are used in real-world applications — industrial automation, automotive, medical, and power delivery?

Reliability & RobustnessMedium-High

Can your design operate reliably across temperature extremes, voltage variations, and 15+ year product lifecycles? TI products go into cars and factories.

Signal IntegrityMedium

Do you understand noise, grounding, filtering, and how to achieve precision in mixed-signal environments?

Tips

  • ▸Study analog fundamentals thoroughly: op-amp circuits, feedback, stability, and noise analysis
  • ▸Understand power management topologies: buck, boost, buck-boost, LDO, and when to use each
  • ▸Be prepared to discuss ADC/DAC architectures: SAR, delta-sigma, pipeline, and their tradeoffs in precision, speed, and power
  • ▸Know TI's embedded processor ecosystem: MSP430 for ultra-low power, C2000 for motor control, and Sitara for Linux applications
  • ▸Practice designing with real-world constraints: temperature range, EMI compliance, and long-term reliability
  • ▸TI serves industrial and automotive markets — understand the qualification standards (AEC-Q100) and why they matter
  • ▸Show you can think at the system level: how does your IC design integrate into the customer's end application?
  • ▸TI values engineers who stay long-term — demonstrate genuine interest in analog and embedded engineering as a career
