Prep interview with peers in the same boat

Cohorlo matches candidates by role, company target, and interview window, then turns that demand into realistic questions, timed scoring, and live peer rooms.

Target-matched cohorts · Timed practice · Live mock rooms.

Start with the right cohort

Tell us what loop you are preparing for so Cohorlo can shape the first rooms around real demand.

Practice first

Timed questions with point scoring.

Work through 30+ tested SQL, product, and strategy prompts. Correct answers earn 100 points inside the timer and 30 points after time expires.

Live interview rooms sorted by topic.

Why this exists

        
Every prep site is only a sliver.

        
Cohorlo keeps the prep loop in one place: realistic practice, peer rooms, verified mentors, and a portable proficiency signal for candidates targeting the same role and company window.

        

          

            
The old way

            
    
              
  • Grind a fixed bank that has not been refreshed in months
    • 
              
  • Run pair sessions with strangers you cannot vet
    • 
              
  • Pay high hourly rates without employer-verification signal
    • 
              
  • Carry no portable proof that your prep is improving
    • 
            

          

          

            
The Cohorlo way

            
    
              
  • Community-authored questions in real company styles
    • 
              
  • Judging that checks correctness, efficiency, and reasoning
    • 
              
  • Verified mentors from the loops candidates are chasing
    • 
              
  • One proficiency rating that follows the whole prep loop
    •
