I applied online. The process took 2 weeks. I interviewed at 360T Trading Networks (Frankfurt am Main) in Oct 2025
Interview
After my initial application almost immedietly ı received a task to complete. It was a Multi-threading task in JAVA. It was over-all pretty hard topic for a junior level to fully be able to pull off. However with modern age of AI, you can get a pretty solid project in.
I completed the task and send it as zip. Next day I recieved an invitation to a first round of technical interview which was 2 weeks later. 2 people were mentioned to be attending.
Interview was about Multi-Threading and Java concurrent library. Only two other question was asked what is Stack and what is the difference between ArrayList and LinkedList.
I believe ı responded as best as ı can. Interviewers 1 opened camera and other did not and only the person who had camera on asked questions.
Questions were not asked in a respective manner but ı did not mind that. Also quite a lot of times interviewer tries to make you second guess your answer and that also was different for me.

Interview
Total 5 stage. 1. take home task 2. Technical round 3. HR round 4. Another Thechnical round, 5. Final round with manager.
Take home task was a socket porgramming task. 1st technical round they focus on java core libraries. I have answered around 85%-90% correct answer but still I got a rejection email. I don't know their expectations. However I noticed they are trying to recruit for this position for a long time (7 months). I really doubt their motivation seeing other candidates posts here.
