## Adaface is "you'll never go back" better

First we’d just like to give a quick nod to the team at Vervoe. They are part of the ecosystem helping companies hire great candidates and have been in the space for a while. So what’s the difference between Vervoe and Adaface? Sure there are features and product stuff that’s different but the biggest difference is how much we care about candidate experience. We want to ensure every candidate leaves the screening experience with a smile. We believe that status quo tech assessment platforms are not a fair way for companies to evaluate candidates. We started Adaface to help companies find strong teammates by assessing on-the-job skills required for a role. We set up 45 min candidate-friendly, custom assessments that test for on-the-job skills.

```Slapchat deployed a new data processing application to the market. The backend part of the application does two specific segments:

- For every new data file submitted by the user, proprietary data cleanup logic is done
- Once data cleanup is complete, proprietary data transformations are done```
`After launching the application for few months, the metrics indicated that the clean up stage of the application is pretty quick while transformation stage takes longer time to complete. In the next phase, the application is being re-written as 2 microservices (’cleanup’ and ‘transformation’). The deployment strategy is to run both on ECS and scale independently. How should the services be integrated?`
```A: ‘cleanup’ publishes data to SNS topic, ‘transformation’ subscribes to the SNS topic

B: ‘cleanup’ sends data to S3 bucket, ‘transformation’ is invoked by S3 event notifications

C: ‘cleanup’ sends data to SQS queue, ‘transformation’ processes messages from the queue

D: ‘cleanup’ sends data to Kinesis Data Firehose, ‘transformation’ reads from the Kinesis Data Firehose```

```A startup company E-Motors is building driverless automated cars. The car contains a sensor that checks the road quality for the next N meters to decide the optimal speed at which the cars should move. We are given recorded data by the sensor in the form of an array, where each element of the array is the rating given to 1 meter of the road in sequence.

The rating given by the sensor is from 1 to 100, where 100 represents the road with the best condition, and any rating above 60 is optimal. Find the longest stretch of road in meters that is categorized as optimal by the sensor.

The input is an array of "strings" which needs to be converted from string to integer/number inside the function.```
