I applied online. The process took 3 months.

The interview process for a Product Support Engineer (PSE) at Samsara is highly comprehensive, consisting of 7 to 8 total rounds split across two main stages: Level 2 (L2) and Level 3 (L3).

• Level 2 (L2) Stage: This initial phase includes a combination of managerial and technical interviews. You must successfully pass all L2 rounds to move forward in the process.
• Level 3 (L3) Stage: Once you are eligible and advance to L3, you will complete another set of managerial and technical rounds to finalize the process.

Samsara’s platform is built on an open-API architecture, heavily utilizing REST APIs and Webhooks to allow customers to integrate IoT data into their own systems. They offer turnkey data connectors for platforms like Power BI, Kafka, Snowflake, and Databricks.

Internally, their software stack relies on Python and JavaScript/TypeScript for web services. To handle trillions of data points, they utilize AWS Kinesis for real-time data ingestion and Spark for big data analytics. Additionally, there is a massive focus on Edge AI, deploying machine learning models directly onto hardware devices for real-time processing.
