New features for recruiters to facilitate the follow-ups process to ideal candidates

Multiple follow-ups and scheduled send in Eightfold AI's email function are two critical features for recruiters. Recruiters can reach out to ideal candidates at the ideal timing more efficiently through these additions. The challenge of the project was how to add features to an existing platform incrementally. This project was my first project during the product design internship at Eightfold AI in the summer of 2019.

The Company

Eightfold AI:
matching qualified candidates through AI

Eightfold AI is an enterprise platform that uses artificial intelligence to identify promising candidates, reach diversity hiring goals, and retain top performers.

The User


Recruiters want to find the right candidate for their company efficiently.

These recruiters often track many potential candidates for one position while sourcing for multiple positions a time. Many recruiters often source their candidate beyond working hours.

May source after working hours

The Problem

The old email client was not efficient for recruiters to follow their leads

Usually, recruiters use the email on our platform after they found qualified candidates for their open positions. However, two major issues stopped recruiters from continuing using the email client throughout the hiring process.

Current system allows only one follow-up

Can’t schedule emails for future delivery

Preliminary Research

Understanding needs and behavior patterns

To further understand the problems and expectations of the clients, we scheduled three client interviews and usability testing of the old design before I started ideation. Aside from the initial feature requests, we discovered a particular insights:

Preliminary Research Insight

Different approaches to customization

There are two major ways of reaching out to matching candidates. Some clients would reach out to a large number of candidates without customization; the other two clients preferred more personalization for a better response rate.


Reach out with default templates

"We'd like to reach out to a bunch of candidates at once to get a better response rate."


Personalization for each follow-up

"People responded to my email if I change the content based on their experience."

Current User Flow

Current Scheduled Send Design Pattern

No users have prior experience for schedule send, so I researched existing products such as Eightfold’s scheduling system and Gmail. And I found out that these scheduling products work similarly. After the user decides on the action, the system will prompt you with a module to select their ideal schedule time.

Design Principles

Building customizations for enterprise users

After gathering the research insights, I established that we want to design the features to be working as default while allowing for customizations to accommodate both types of users.

Effective with the default template while being easily customizable

Explicit information presentation to prevent errors

Updating visual design to be consistent with the rest of the platform


Developing for both types of users

How might we design a multiple follow-up experience for both maximizers and satisficers?

From the user interview, we decided to prioritize the major steps of the contacting process: the template, the email module, and scheduled sent. There are users who would reach out to a large number of candidates without changing the individual content, so we wanted to prioritize making sure the multiple follow-up feature works properly from an existing template. Then the user can customize the content in the current email module and choose if they want to send the email right away or send it in the future.

Testing and Iterations

Key design decisions and iterations

Based on the three external with our clients and two internal user ability tests as well as three design reviews, I went through many different explorations and iterations according to the feedback from the clients and directors.

Scheduled send

As the most technically independent new feature, we designed the scheduled send first. From designing the most idea interaction to scoping down to an MVP, the development of the scheduled send button aligned the user goal and technical limitations.

  • A familiar button design

    Adopted an existing style of schedule send button inspired by Gmail's design to reduce the cost of transition.

  • Ideal scenario: following up at the highest replied time

    Suggested an optimal delivery time from our prediction to achieve the recruiters' goal.

  • MVP: following up in the next two days

    Default send time to the next two days (rather than highest replied time or business day) for the initial launch.

  • Be more explicit to prevent possible errors

    Explicit showing the relationship between initial contact and follow-ups to reduce possible confusion.

  • Sending as a specific person rather than a role

    Keeping sender to a list of people with permission rather than their roles within the company to minimize the technical requirement for the initial release.

  • Optimizing the order of information for the user

    Finalize the sequence of delivery time based on multiple user feedback.

  • Utilizing tabs organize different follow-ups

    By adding a tab navigation, users can manage information of the initial email and each follow-up individually.

  • Preventing accidental overwrite

    Separating the original "Save Template" button into two buttons to solve the pain point of accidentally overwrites the currently-used template without a confirmation.

  • Moving tabs to the bottom to match how users compose emails

    From usability testings, we discovered that most users thought about the follow-ups after they finish editing the initial outreach. Thus, we moved the tabs to the bottom of the window to accommodate users' writing behaviors.

Final Results

Multiple Follow-up Email Module

Integrating tabs to track multiple follow-ups

By using a tab system to the email module, users are able to keep track of the initial email and multiple follow-ups easily. They can also edit individual follow-up without changing the template. For the initial launch of the feature, we limited the ability to edit the number of follow-ups to not only reduce the adaptation period but also prevent spamming.

Multiple Follow-ups Template

Collapsing multiple follow-ups while showing the essential information

The design for this template editor focuses on making sure that the users understand each customization, such as sending time and sender. Also, I minimized the information load on a single page for the amount of content through accordions.

Schedule Send

Customized scheduling with recommendations

Similar to Gmail, the schedule send button is located on the side of the original send button as an alternative. Users can decide an ideal time themselves or select one of the given recommendations based on the following working hours.

Successfully launched at the end of August

The schedule-send feature was launched in July, and the rest of the redesign email features were launched at the end of August.

"Looking forward to playing around with the new feature. Thank you for all that you, your team and the company are doing to accommodate and push innovation on your platform. If I haven't said it before, I want to say that is an absolute pleasure to be working so closely with Eightfold!"

Learning from designing for Eightfold AI

It was a pleasure to intern as a product designer at Eightfold AI. I was able to own most of my projects throughout the internship as an intern, which means I got the opportunity to design in a realistic environment sooner than other interns. Thus, I found two major takeaways from this internship.

Constant communication is the key to a smooth development process

During the time of working as a product designer on all projects in the summer at Eightfold, I found myself valued communication even more than before. Because I was often the only designer for these new features, I checked in regularly with the PMs and the engineers to not only update them about my progress but also see if there were any blocks that I need to be aware of for continuing my design. Having this kind of constant communication made my design process extremely adaptive, and it also encouraged others to approach me with any issues.

Tradeoffs between technical limitations and ideal designs

Compared to school projects, I learned a lot from how to negotiate the tradeoffs between technical resources and user expectations. There were clients that expected a comprehensive product, yet there were also other technical priorities within the company. How to distill the core features and interactions that the users satisfy was one of the best learning experiences I got from this internship.
