DEKA Research and Development Senior Software Engineer interview questions

Application was quickly followed up with an hr level phone interview. Then a 2 weeks wait before hearing back for a follow up interview with engineering team. Team asked about qualifications and later asked tricky questions to see applicants thought process. 1 week later I had my first offer below asking salary. I countered the offer and waited 2 weeks to hear back from hr. Job accepted but overall a long process with lots of waiting.
