Intercom has a selection process where before you have an interview you are going to have to do some work. This is already a filter to eliminate people less motivated with the company.

You have to write your proudest achievement and solve a technical problem (filter customer records from a JSON file). You can find more information on their website, search for "intercom how we hire engineers".

The screening interview:

• Why Intercom?
• What is your role in your current company?
• What are you working on right now?
• What is a project you are proud of?

Video technical interview (live coding):

• Write a factorial function
• Write an alternative factorial function
• Find the pairs of numbers that added together give the objective. Given [0, 12, 4, 8] -> Expected 12: [(0, 1) (2, 3)]
• Why Intercom?
• Describe a large project that you have worked on over the past 12-18 months
• How did you overcome the problems?

Cultural interview:

• When did you do something that is not expected from your role/position?
• Tell me about a mistake in the past. What did you do differently?
