Received an email from recruiter after submitting application on their site. The Recruiter did not use a valid email address to initiate contact or set up the phone call. This made it difficult to confirm the time for the call or ask any questions. I eventually Had to contact the general service desk to communicate that I had no way of reaching the recruiter. After receiving contact from the recruiter, I had to configure an awkward conferencing software on my phone. After entering the conference the recruiter indicated that it was mandatory for me to turn on a digital camera for the interview to proceed. Since I was in an awkward position, and not wearing a suit, the camera was not an option. Considering that the recruiter refused to share details about the position without a webcam session I decided to discontinue my application.
Feeling thrilled to have accepted the offer, I look back on this interview process as both challenging and rewarding. It began with a technical round where I tackled a complex A/B testing design question, followed by a SQL query on user retention. The final stages included a system design discussion that had me sweating, but honestly, the system design section on PracHub prepared me well. Each step pushed my limits, but the culmination was definitely worth it, landing me a role at Microsoft.

Phone screen with HR/recruiter. Less than 10 mins. Very basic mostly about role fit and my background and resume. Did not hear back from them at all. Very unenthusiastic during the call
