SI Government Solutions Senior Cyber Engineer Interview interview questions

Applied through a glassdoor referral. After about a month a phone screen was scheduled. Phone screen had a few low level C++ coding questions (macro def, endianess) and some higher level such as find the greatest return for a year of stock returns. Emailed HR asking for expected decision date and any feedback. Got nothing back. Very unprofessional. Received an automated email saying I was no longer being considered.
