This was the worst interview experience I've ever had. The interview had 7 rounds spread over 3 months, all in the US time zone. After the final round, there was no communication for 3 weeks. When I followed up, they told me they no longer needed a staff engineer and were looking for a lower-ranked role instead. Extremely unprofessional company. I'd advise never to waste your time interviewing with this unprofessional organization.

Coding System Design Behavioral
it was a standard interview experience, starting with a recruiter call, followed by a screening, and then 4 rounds covering system design, coding, behavioral questions, and a manager chat. The whole process was smooth, and the recruiter was very responsive. It took about 6 weeks from the internal referral to get the interview.

Technical Coding Behavioral
Got an email from the hiring manager after they found my resume on a job site (maybe monster). Then had a phone screen with the hiring manager where we discussed various OS and networking topics. After that, I had an onsite interview with the hiring manager and five engineers. One of them asked about what happens when you type 'ls', another about pointer scenarios, another about reversing a linked list, and one more about something involving a hash table.
Confirmed questions4 questions
- Can you explain what happens when the command 'ls' is executed?
- Could you describe different scenarios involving pointers?
- How would you go about reversing a linked list?
