Salesforce Technical Architect interview questions

Applied online and also asked my friend in Salesforce to refer me. Got a call from internal recruiter of Salesforce within a week who scheduled telephonic round to evaluate role and culture fit. After basic round of interview while checking my experience match for the requirements of role, I was scheduled for technical round with Program Architects. Two PAs interviewed me who asked varied set of technical questions from security, SSL, On premise & cloud connectivity, design patterns, ETL, best practices of Apex. Best was rapid fire round in the end. It was well utilized 1 hour interview. I was informed about the interview results within 1 day and next final round with Directors was scheduled in 2 weeks. Director level interview was all about verifying consulting experience, culture and role fit. It was 40 mins round and expected to discuss experience in client/stakeholder handing, difficult customers.. After 3 days I got call from recruiter about the results and I WAS SELECTED! It has been amazing journey of 6 weeks of interviews and felt content after clearing all of the rounds. Advise for Preparation: Read all about the Job Description and plan your preparation well around certified Technical Architect. I spent 2 months in preparation which was well paid off.
