I did have a job interview and was declined because I wasn't knowledgable about middleware they claim, here is an explanation:

JBoss vs Weblogic vs Websphere

Enterprise architects and other IT decision makers are often faced with important decisions to make regarding the best application server / web server platform for IT. The market leaders are Websphere, Weblogic and JBoss. Here is a brief overview and comparison of each. 

JBoss is Red Hat's application server platform and comes in both open source and paid subscription versions. JBoss is the only option of the three if open source is an important consideration. The free version of JBoss called JBoss Community benefits from the open source community and has strong support in the ISV community with related technology like RichFaces. The paid license version called JBoss Enterprise supports mission critical functionality and has certified platforms. If your team is considering certain java frameworks from RedHat such as Seam, jBPM or RichFaces, JBoss should be your choice. JBoss also has strong support for Hibernate.

Operating System:
Programming Language:
JBoss Application Server (or JBoss AS) is a free software / open source Java EE-based application server. Because it is Java-based, JBoss AS is cross-platform, usable on any operating system that Java supports.
JBoss AS 4.0 is a Java EE 1.4 application server, with embedded Apache Tomcat 5.5. Any Java Virtual Machine between versions 1.4 and 1.5 is supported. JBoss can run on numerous operating systems including many POSIX platforms (like Red Hat Enterprise Linux and MacOS X), Microsoft Windows and others, as long as a suitable JVM is present.
JBoss AS 4.2 is also a Java EE 1.4 application server, but Enterprise JavaBeans 3.0 is deployed by default. It requires the Java Development Kit version 5. Tomcat 6 is bundled with it.
The next version of JBoss AS 5 will be a Java EE 5 application server.

Weblogic is Oracle's application server acquired in the BEA acquisition. Weblogic has a long history very strong support for high end architecture features such as clustering and scalability. Weblogic has formed the delivered underlying application server architecture to many Oracle applications such as PeopleSoft although this is now changing with Oracle Fusion Middleware. Oracle has begun to rebrand Weblogic more of as a basis for application grids, a testament to its strong scalability and clustering functionality whereas Fusion Middleware is Oracle's plug and play architecture. Weblogic has the best integration with other Oracle products such as Fusion Middleware, Oracle database and Oracle applications.

Operating System:
Owned by BEA Systems, Inc, BEA WebLogic is a J2EE Platform product family that includes:
Weblogic, Inc., was founded by Paul Ambrose, Bob Pasker, Laurie Pitman, and Carl Resnikoff, in September, 1995
Up until then, Ambrose and Resnikoff had been developing (pre-JDBC) Oracle, Sybase, and Microsoft SQL Server database drivers for Java under the name dbKona, as well as a "three tier" server to permit applets to connect to these databases.[1]. This was the WebLogic 1.48 server, and was called T3Server (a bastardization of 3-Tier Server).
Concurrently, Pitman and Pasker had been working on network management tools in Java. Pasker had written an SNMP stack in Java and a W32 native method for ICMP ping, while Pitman worked on applets to display the management data.
One of the hidden features of the 1.48 server version was the ability to extend it by modifying a dispatcher and adding a handler for different types of messages. Pasker talked Ambrose into sending him the source code for the server, and Pasker extended it so that Applets could make SNMP and PING requests on the network, and display the results.
At this point, the founders worked together to pursue what was eventually to be called the Application Server.

BEA Systems acquired WebLogic, Inc. in 1998, following which it became BEA WebLogic. Oracle acquired BEA in 2008, following which it became Oracle WebLogic.
BEA Weblogic Application Server versions:
  • WebLogic Server 10.3 Tech Preview
  • WebLogic Server 10.0
  • WebLogic Server 9.2
  • WebLogic Server 9.1
  • WebLogic Server 9.0
  • WebLogic Server 8.1
  • WebLogic Server 7.0
BEA Weblogic Server is part of the BEA Weblogic Platform and supports Oracle, DB2, Microsoft SQL Server, MySQL Enterprise and other JDBC-compliant databases. The other parts of WebLogic Platform are:
  • Portal which includes Commerce Server and Personalization Server
  • Weblogic Integration
  • BEA Workshop, an Eclipse IDE for Java, SOA and Rich Internet applications
  • JRockit, a JVM for Intel CPUs.
Weblogic Server includes .NET interoperability and supports the following native integration capabilities:
BEA Weblogic Server Process Edition also includes Business Process Management and Data Mapping functionality. Weblogic supports security policies managed by Security Administrators. The BEA Weblogic Server Security Model includes:
  • Separate application business logic from security code
  • Complete scope of security coverage for all J2EE and non-J2EE components
Supported open standards

Websphere is IBM's application server. IBM offers a free WebSphere Application Server Community Edition along with an paid license Enterprise Edition. In many ways Websphere is a family of products ranging from SOA embedded server appliances to E-Commerce editions. IBM treats Websphere as a product platform supporting many product lines. Therefore Websphere is a nice choice if your needs fit a product line such as you are building an custom eCommerce website. Websphere also supports very high end architecture features such as clustering and high scalability. 

IBM WebSphere explained
WebSphere refers to a brand of IBM software products that are mostly proprietary[1], although the term also popularly refers to one specific product: WebSphere Application Server (WAS). WebSphere helped define the middleware software category and is designed to set up, operate and integrate e-business applications across multiple computing platforms using Web technologies. It includes both the run-time components (like WAS) and the tools to develop applications that will run on WAS.
