## Notes
|
||
I'm going through handwritten notes of the past months and put learnings in here:
|
||
- Talk with Jonathan (Friend of Josias Zeller)
|
||
- Talked about Hexagon and that it's not the best company,
|
||
- Now at Sevensense (acquired by ABB)
|

Grosser und langer Tag.
|
||
Ich hatte ein Vorstellungsgespräch bei Embotec, welche autonome Lastwagen entwickeln, um in Häfen und auf anderen Privatgründen Missionen zu erfüllen. Das Vorstellungsgespräch (Interview) war gut und ich glaube ich habe mich gut verkauft. Die Position ging um Systems Integration Engineer, welche verschiedene Disziplinen zusammen führt. Das ist auch worin ich gut geworden bin in den letzten Jahren und durch die Erfahrung bei OneSec.
|
||
- Sie sind auch nicht gut organisiert (Jira, etc), obwohl es eine besser finanzierte Firma ist: Vielleicht machen wir mit OneSec doch nicht alles schlecht.
|
||
- Es gibt viele blackbox Systeme für Robotik (wie Fixposition), von welchen man SLAM bekommt ohne eigene Entwicklung machen zu müssen
|
||
- System so bauen das Kalibrierung nicht nötig ist: Kamera und Lidar angeordnet, dass sie radial aliniert sind.
|
||
- Die Interviewfragen habe ich glaube ich gut beantworten können. Die Vorbereitung kurz davor mit ChatGPT war wichtig.
|
||
- Ich habe oft mit Requirements argumentiert um verschiedene Fragen zu beantworten. Das hat Sven sehr gefallen
|
||
- Ich konnte den Unterschied zwischen [[Path Planning]] und Motion Planning nicht sehr gut erläutern
|
||
- Ich kannte das Konzept von recursive feasibility nicht. Das war die einzige Frage zu der ich gar keine Idee hatte was ich sagen sollte.
|
||
- Fragen topics: Motion planning, lidar pipeline: from raw data to fusion to smart algorithms, etc, early vs late fusion. Dann hardware: wie system aufbauen? Er hat positiv auf debugging capabilities reagiert, da das auch kosten sparen kann. Technical debt: wann kann technical debt gut sein?
|
||
- Die Bücher [[More Effective Agile by Steve McConnell]] und [[Software Project Survival Guide by Steve McConnell]] haben mir geholfen mehrere Fragen gut zu beantworten.
|
||
- Die Leute waren sympathisch. Aber es hat so gewirkt, als ob sie manchmal auch alleine sind. Es war sonst niemand da.
|
||
- Sie arbeiten mit customer, anstatt alles selbst zu entwickeln, was schlussendlich niemand will. Das gefällt mir besser als bei [[OneSec]]. Doch

||
> ### **Technical Questions**
|
||
> 1. **System Integration Basics:**
|
||
>
|
||
> - Can you describe the process of integrating a new sensor or actuator into an existing autonomous system?
|
||
> - How would you approach debugging a system where components from different vendors fail to communicate?
|
||
> 2. **Autonomous Systems:**
|
||
>
|
||
> - How do you handle the challenges of integrating perception, planning, and control modules in an autonomous vehicle?
|
||
> - What are the key considerations for sensor fusion in autonomous trucks?
|
||
> 3. **Communication Protocols:**
|
||
>
|
||
> - What communication protocols have you worked with (e.g., CAN, Ethernet, ROS2, etc.), and how did you handle compatibility issues?
|
||
> - How would you prioritize between low-latency and high-bandwidth communication in a vehicle network?
|
||
> 4. **Safety and Redundancy:**
|
||
>
|
||
> - How do you ensure the reliability of safety-critical systems during integration?
|
||
> - Describe a situation where you implemented redundancy in a hardware or software system.
|
||
> 5. **Software and Tools:**
|
||
>
|
||
> - What tools do you use for testing and simulating system integration (e.g., Gazebo, MATLAB, dSPACE)?
|
||
> - Have you worked with Docker or similar tools for modularizing system components?
|
||
> 6. **Troubleshooting:**
|
||
>
|
||
> - How would you diagnose and resolve an issue where an autonomous truck intermittently fails to detect obstacles?
|
||
> - What steps would you take if you discovered a hardware-software interface mismatch during system testing?
|
||
> 7. **Hardware Experience:**
|
||
>
|
||
> - Have you integrated LiDAR, cameras, or radar into a vehicle system? How did you calibrate and test them?
|
||
> - How do you approach integrating hardware from multiple suppliers into a unified system?
|
||
>
|
||
> ### **Scenario-Based Questions**
|
||
>
|
||
> 8. A customer reports that an autonomous truck in their fleet frequently stops unexpectedly. How would you troubleshoot and resolve the issue?
|
||
> 9. You’re tasked with integrating a new braking system that has a different communication protocol than the existing vehicle controller. How would you approach this?
|
||
> 10. If a sensor data stream becomes unreliable, how would you design the system to handle this situation while maintaining safety and performance?
|
||
>
|
||
> ### **Project Management and Teamwork**
|
||
>
|
||
> 11. How do you manage integration projects to meet deadlines without sacrificing quality?
|
||
> 12. Describe a time when you worked in a cross-disciplinary team to integrate a complex system.
|
||
> 13. How do you ensure proper documentation during the integration process for future troubleshooting or upgrades?
|
||
>
|
||
> ### **Industry-Specific**
|
||
>
|
||
> 14. How would your integration process differ for autonomous trucks operating in a harbor versus on public roads?
|
||
> 15. What are the specific challenges of operating autonomous vehicles in industrial environments like harbors, and how do you address them?
|
||
>
|
||
> ### **Behavioral Questions**
|
||
>
|
||
> 16. Tell us about a time when you encountered a major setback during a system integration project. How did you handle it?
|
||
> 17. How do you prioritize tasks when multiple components need simultaneous attention during integration?
|
||
> 18. Describe a situation where you had to explain technical details to non-technical stakeholders.
|
||
>
|
||
> ### **General**
|
||
>
|
||
> 19. What is your experience with regulatory requirements for autonomous systems, such as ISO 26262 or functional safety standards?
|
||
> 20. How do you stay updated on the latest technologies and methodologies in system integration and autonomous systems?

[[Emanuel Perrig|Emanuel]] hat mich angerufen und mich nach Rat gefragt bezüglich Beziehung. Er konnte sich erinnern, dass ich einmal gesagt habe, dass ich nie Schmetterlinge im Bauch gespürt habe und dass ich trotzdem in einer Beziehung bin. Sein jetztiges Date hat einen sehr ähnlichen Spruch gesagt.
