Charles Schwab Software Developer interview questions

Interview was very smooth. Starting with phone screening with recruiter then panel interview with manager and team. Received an offer a week after the panel interview. Panel members were very calm and I did not feel any stress as I talked to them about my background or questions they asked.

First, there was a phone call with recruiter. This didn't seem to go anywhere until i was randomly contacted by a hiring manager for an entirely different role. Had a short phone screen and was passed on to a technical challenge. Technical challenge: No online environment was set up and I was told I HAD to use C# and share my screen. There were issues with my webcam and I wanted to reschedule since about 20 minutes was wasted trying to get software to recognize webcam did exist and was connected to my computer (it worked on other software on computer). Would not reschedule and forced interview forward. NONE of the 3 interviewers put on their webcams which i found very unprofessional. Asked some Angular/C# questions and then picked a random algorithm. Took 3 weeks to get back to say they passed on me.
