QuEST Global vs LTTS: overview
QuEST Global
QuEST Global was founded in 1997 and is headquartered in Singapore, operating over 90 delivery centers across 18+ countries and serving a very broad set of industries — aerospace and defense, automotive, energy, hi-tech, healthcare, rail, and semiconductors. Reported employee counts vary substantially by source (roughly 21,500 to over 32,000), which is itself a useful signal for a buyer: a firm this large and this diversified doesn't lend itself to a single precise headcount figure the way a boutique does. Embedded and silicon engineering is offered directly to chipmakers as part of end-to-end services, but it's one capability among the firm's many vertical practices rather than a dedicated embedded specialty.
LTTS
L&T Technology Services was incorporated in 2012 as a subsidiary of the Larsen & Toubro Group (with engineering heritage back to 2006 as L&T Integrated Engineering Services) and went public via IPO in 2016. Headquartered in Vadodara, India, LTTS reports roughly 23,800 engineers across 22 global design centers, with embedded systems and semiconductor engineering as one of several business lines alongside automotive engineering, industrial IoT, manufacturing plant engineering, and medical engineering. For a procurement team, the publicly-listed status is a genuine differentiator versus most other firms on this list — audited financials and governance disclosures that a private consultancy can't provide — but it also means embedded work competes internally for resourcing against several equally large business lines.
