I applied through an employee referral. I interviewed at Real-Time Innovations (Frankfurt am Main) in Feb 2026
Interview
3 months interview process, 6 interview rounds including a presentation round.
The interview process at Real-Time Innovations was structured, professional, and overall a positive experience. It consisted of multiple stages, including an initial technical screening, followed by deeper technical interviews covering automotive systems, networking concepts, and a coding exercise. There were also behavioral and sales-fit discussions focusing on customer interaction, communication skills, and motivation for the FAE role.
One round involved a technical presentation, where I was able to choose a topic related to my expertise. This was followed by detailed Q&A with a panel, assessing both technical depth and the ability to explain complex topics clearly.
Throughout the process, the interviewers were knowledgeable, supportive, and genuinely interested in understanding my background. Communication from HR was prompt and transparent.
Overall, the process strongly emphasizes problem-solving ability, system-level thinking, and the capability to bridge technical and customer-facing responsibilities. Before the offer referral check from 2 coworkers was also included in the process.
Interview questions [1]
Question 1
Initial Screening technical questions:-
- Limitations of SOME/IP & how does DDS address them ?
- TCP vs UDP ?
- How does Data centric architectures help with modern SDV systems ?
- Does data filtering exist on the databus(RTE) of Classic Autosar ECUs ?
Technical interview questions:-
- Automtoive:
Tell me how does Automotive SW development process looks like ?
How to integrate DDS on an Classic AUTOSAR ECU?
- Networking:
Are Multicast & broadcast the same ? Are they used in same context ?
How should you send a msg in order for it to be broadcasted ? Ans: you use the last IP on the IP Address range 255.255.255.255
Why do you think CAN should be replaced in Legacy ECUs for DDS integration ?
- Coding round
Can you send and recieve on CAN, SPI at the same time ? Concurrency ?
Mutithreading etc. Semaphore, mutex, OS fundamentals
Presentation round:
- Explain what data centric architectures actually means to you in terms of modern Automotive SDV architectures ?
- What is a Classic AUTOSAR based ECU a deterministic system ? What makes it deterministic ?
I applied through other source. The process took 3 weeks. I interviewed at Real-Time Innovations (Sunnyvale, CA) in Oct 2019
Interview
Contacted by in-house recruiter based on LinkedIn profile. Emails to setup initial phone screen with the hiring manager. Then 2 more phone screens. Then in-house for 7 interviews (including a lunch interview). Plus a 30 minute technical presentation (I could pick the topic). In-house was handled in a single day. It was well structured.
